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.

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

justus:

I multiplied the second equation by -2

justus:

to get −4x − 12y = −48.

justus:

what do you think the correct option is?
