Question

Given the following system of equations:

−4x + 8y = 16
2x + 4y = 8

What action was completed to create this new equivalent system of equations?

−2x + 4y = 8
2x + 4y = 8

Multiply the second equation, 2x + 4y = 8, by −1.
Multiply the first equation, −4x + 8y = 16, by −1.
Divide the second equation, 2x + 4y = 8, by 2.
Divide the first equation, −4x + 8y = 16, by 2.

Answer 1

Answer: The correct option is D.
