Which method would be best (quickest) for solving the system below:
3x - 4y = -2
y = 2x + 1

Answers

To solve with Elimination:

Write the equations under one another, like this:

2x - y = -1
+ 3x + 4y = 26

Ideally, we would like for one of the variables to be eliminated when we add vertically (straight down). But if we add them as they are this does not happen. We must manipulate one of the equations so that it will happen. Again, you can try to eliminate either x or y. I always look for a term that has a coefficient of 1 (or negative 1). So, let's use that y from the first equation again.

If the coefficient of the y in the other equation is POSITIVE 4, then I need the coefficient from the first equation to be its opposite, NEGATIVE 4. To do this, simply multiply the first equation by 4, this will create MAGIC!

4( 2x - y = -1)
+ 3x + 4y = 26

Be certain to Distribute across the entire first equation, so multiply all three terms by 4.

8x - 4y = -4
+ 3x + 4y = 26

Now add straight down (vertically). The y term will be eliminated.

11x = 22

Divide both sides of the equation by 11.

x = 2

Almost there! Now, substitute the 2 in for x in either of the original equations. Either one will work. I'm gonna use the second equation.

3x + 4y = 26

3(2) + 4y = 26

6 + 4y = 26

Subtract 6 from both sides of the equation.

4y = 20

Divide both sides of the equation by 4.

y = 5

That's it! There it is again. Put it all together. If x = 2 and y = 5, then the solution is the ordered pair, (2,5).

Answer:

[tex]y = 5 + x[/tex]

[tex]y - x = 5[/tex]

[tex]x = y - 5[/tex]

Step-by-step explanation:

No options were given but the question can still be solved

Given

From the first statement, we have:

[tex]Maria = x[/tex]

From the second, we have:

[tex]Anika = 5\ more[/tex]

Required

Determine the relationship between the amount of rice they bought

5 more means 5 + Maria.

So, [tex]Anika = 5\ more[/tex] becomes

[tex]Anika = 5 + Maria[/tex]

Substitute x for Maria

[tex]Anika = 5 + x[/tex]

For proper expression, let Anika be y

[tex]y = 5 + x[/tex]

Subtract x from both sides

[tex]y - x = 5[/tex]

Make x the subject

[tex]x = y - 5[/tex]

Answers

Answer:

$385

Step-by-step explanation:

7x$40=280

3x$35=105

280+105=385

Answer:

$385

Step-by-step explanation:

If for the first seven days Joe has to pay $40, you would multiply that number by seven to get $280. However, he had the car for 3 extra days so you would multiply the additional cost of $35 per day by 3 to get $105. After that all you have to do is add $280+$105 to get a total of $385.
