The value of y in the solution for this system of equations is -61/13.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
2x – 3y = 13 and y = 5x - 2
Solving the Two Equation we get
2x - 3(5x -2) = 13
2x - 15x + 6 = 13
-13x = 13 -6
-13x = 7
x= -7/13
and, y= 5(-7/13)- 2
y = -35/13- 2
y = -61/13

Bert has three times as much money as Ernie. If Ernie spends $6 on a new rubber ducky, then Bert will have five times as much money as Ernie. How much money does Bert have?
Answer:
Bert has $45.
Step-by-step explanation:
I have no real strategy, except for that I used guess and check. How did I do this? Well, since I am in 5th Grade, I don't know algebra very well, so I made an organized chart and checked all the numbers that had to be a multiple and could be divided equally by 5, 3 and when a third of that number was subtracted by 6, it was a fifth of the orginal number. Thats how I got 45.
Checking this answer:
It is always important to check your answer after finishing the problem, so this is how I checked my answer:
1. 45 divided by 3 = 15
2. 15 - 6 = 9, and 9 is 1/5 of 45
Bert has $45.

what is the measure of <x
Answer:
14°
Step-by-step explanation:
We know that ∠PQS is a right angle.
We also know that ∠PQR is 76°.
So, to find ∠RQS, we can do 90°-76° = 14°
x° = 14°
Answer:
[tex] \huge{ \boxed{ \bold{ \tt{x = 14 \degree}}}}[/tex]
Step-by-step explanation:
♨ First , let's know about complementary angles :
Two angle are said to be complementary if the sum of their measures is 90° .The best way to think of a complementary angle is ' L - Pattern ' .✎ Now, set up an equation and solve for x :
[tex] \sf{x \degree + 76 \degree = 90 \degree}[/tex]Move 76° to R.H.S ( Right Hand Side ) and change it's sign

Which statements about opposites are true?
Select each correct answer.
Answer:
(a) TRUE
(b) TRUE
(c) FALSE
(d) TRUE
Step-by-step explanation:
" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".
(a) TRUE
Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0
(b) TRUE
this could be seen clearly from the number line.
(c) FALSE
this statement is false since we can take example of zero.
the opposite of zero is 0 but 0×0≠1.
(d) TRUE
since 0-0=0.Step-by-step explanation:

whats the x-intercept of y=4 − 3/5x
Answer:
x=6 2/3 So (6 2/3, 0)
Step-by-step explanation:
The [x] intercept of the line would be 20/3.
What is the general equation of a Straight line?
The general equation of a straight line is -
y = mx + c
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have the equation of the line as -
y = 4 - (3/5)x
We can write the equation as -
y = -(3/5)x + 4
For [x] intercept -
y = 0
-(3/5)x + 4 = 0
4 = (3/5)x
x = (4 x 5)/3
x = 20/3
Therefore, the [x] intercept of the line would be 20/3.

Is 11 a solution to 3(x+6)=4x ?
Answer:
The number 11 is not a solution for the given equation.
Step-by-step explanation:
We are given an equation with one variable. We can use simplifying processes to solve the equation.
[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]
We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.
[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]
Therefore, 11 is not a solution for the given equation.
Answer:
First of all,We need to find the value of x to find that 11 is the solution to 3(x+6)=4x or not.[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]
[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]
[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]
[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]
Let's put x as 11:[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]
[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]
[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]
51 doesn't equal to 44.So,11 is not the correct solution to 3(x+6)=4x.Which situation shows a constant rate of change?

The sum of three numbers is 56. The second number is 2 times the third. The first number is 8 less than the third. What are the numbers?
Answer:
X = 8
Y = 32
Z = 16
Step-by-step explanation:
X + Y + Z = 56
Y = 2Z
X = Z – 8
Substitute the values from the second and third equation into the first equation:
Z – 8 + 2Z + Z = 56
Simplify
-8 + 4Z = 56
4Z = 64
Z = 16
So if Y = 2Z, Y = 2(16) = 32
And if X = Z – 8, X = 16-8 = 8

1. -25/4 DIVED -5 5/4
2. -3/21 x -3
Answer:
EZ PZ bruh
Step-by-step explanation:
First one, -25/4 ÷ -5 5/4
change the second mixed fraction into an improper one
=> -25/4 ÷ -25/4; dividing a number by itself gives you '1'
=> 1
second question,
=> -3/21 × -3; multiply the numerator with the other numerator, and since there is nothing given in the denominator of the second number mean its 1, hence multiply the denominator with the other denominator, and we get:
=> 9/21; we simplify this fraction and get: 3/7

How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The given equations are as below,
y = 2x + 6 (1)
y = 6x - 10 (2)
In order to find the variable x, equate equations (1) and (2) as follows,
2x + 6 = 6x - 10
⇒ 6x - 2x = 10 + 6
⇒ x = 4
Hence, the value of x is obtained as 4.

Solve the equation for x. 3x - 5x+ 5 = 20
Hey there!
3x - 5x + 5 = 20
• First COMBINE your LIKE TERMS
(3x - 5x) + (5) = 20
3x - 5x = -2x
• NEW EQUATION:
-2x + 5 = 20
• SUBTRACT by 5 on BOTH SIDES
Like: -2x + 5 - 5 = 20 - 5
Cancel out: 5 - 5 because that gives you a 0
Keep; 20 - 5 because it helps us solve for your x
**20 - 5 = 15**
• NEW EQUATION:
-2x = 15
• DIVIDE by -2 on BOTH SIDES
2x/-2 = 15/-2
Cancel out: -2x/-2 because that gives you 1
Keep: 15/-2 because it helps us solve for x (it also gives the value of “x”)
**AFTER SOLVING ABOVE WE FOUND OUR ANSWER**
Answer: x = -15/2 ✅
