Question

What could you multiply the first equation by to help you form a zero pair and eliminate the x variable?A. 3B. -3C. 4D. -4

Answer 1

Given equation

x+y=-2

3x+4y=-11

Multiplying the first equation by -3 we have,

-3x-3y=6

Thus adding it with the second equation

y=5

Thus x is eliminated.

The answer is B.-3
