Question

Given the system of equations presented here:

4x + y = 4
2x + 6y = 24

Which action creates an equivalent system that will eliminate one variable when they are combined?

Multiply the first equation by −4 to get −16x − 4y = −16.
Multiply the second equation by −4 to get −8x − 24y = −96.
Multiply the first equation by −2 to get −8x − 2y = −8.
Multiply the second equation by −2 to get −4x − 12y = −48.

Answer 1

4x+y=4
2x+6y=24

4x+y=4
-4x-12y=-48
11y=-44
y=-4

Now put the y in the first equation

4x+(-4)=4
4x-4=4
4x=8
x=2

Answer 2

I multiplied the second equation by -2

Answer 3

to get −4x − 12y = −48.
