Ellason wants to solve the following system using the elimination method:

Question

5x + 2y = 30
x + y = 8

What number should the equation x + y = 8 be multiplied by to eliminate y? (4 points)

2

−2

5

−5

Answer 1

To eliminate y, you should multiply the equation x + y = 8 by −2. This will give you:

-2(x + y) = -2(8)
-2x - 2y = -16

This equation can then be added to the first equation to eliminate y.

Answer 2

thats not the question

Answer 3

I apologize for that mistake.

To eliminate y, you should multiply the equation x + y = 8 by -2.

So the correct answer is: -2
