solve 4x-3 = 2x+7.​

Answers

Answer 1

Answer:

x=5

Step-by-step explanation:

4x-3 = 2x+7.​

Subtract 2x from each side

4x-2x-3 = 2x-2x+7.​

2x-3 = 7

Add 3 to each side

2x-3+3 = 7+3

2x= 10

Divide by 2

2x/2 = 10/2

x = 5

Answer 2

Answer:

x=5

Step-by-step explanation:

4x -3 = 2x +7

Let's start by getting the 2x away from the seven. Subtract the 2x from itself and from 4x. We will subtract 2 because a negative will cancel out the positive.

2x -3 = +7

Now let's get the -3 away from 2x. Add 3 to the -3 and the +7. We will add because a positive will cancel out the negative.

2x = +10

Then divide +10 by 2 to get the final answer.

How many solutions does the system below have?
2x + 6y = 12
y =

1 solution
2 solutions
no solutions
infinite solutions

Answers

Answer: 1 solution

An augmented matrix for the system is
[2,6,12;1,1,2] where we will call the first two columns A and the third b. A is linearly independent since it is row equivalent to the identity matrix, which tells us that for any b there will be a unique solution (x,y).

assume that a varies directly as b. when the value of a is 5 the value of b is 18. when the value of a is 22 what is the value of b?

Answers

Answer:

The value of b when a is 22 is 79 1/5

Step-by-step explanation:

a varies directly as b

Let k be the constant of proportionality;

then;

a = kb

5 = k * 18

k = 5/18

Finding the value of b, when a is 22

22 = 5/18 * b

5b = 18 * 22

b = (18 * 22)/5 = 79 1/5

remove the parentheses and collect like terms

9m-12-3m=3m-18

collect the terms

3/2+1/2x=2x

3/2+1/2=2x

2=2x

1=x

Answer:

2 = x

Step-by-step explanation:

3/2 + 1/2 times x = 2x

x by itself = 1x

Subtract 1x

3/2 + 1/2 times 1x - 1x = 2x -1x =

3/2 + 1/2 = 1x

3/2 + 1/2 = 4/2 = 2

2 = 1x

1x/1 = x

2/1 = 2

what does k= 9k=8k-6

Answers

k=−6 ok I think that is

Answer:

Alright, so we got k + 9k = 8k - 6.

This means that 10k = 8k - 6.

As a result, we have 2k = -6, and k = - 6/2 = -3

So, k = -3 :)

substitution method.
x = 4y - 94
