Question

Select the best possible first step to solving the system by first eliminating the y variable.

5x – y = 5
7x – 3y = –1

A. Multiply the first equation by –3.

B.Multiply the second equation by –3.

C. Multiply the first equation by 3.

D. Multiply the second equation by 3.

Answer 1

we want it so that when we add the equations together the y variable goes away
and on the bottom equation you have -3y
so we want the top equation to have +3y
so multiply the first equation by -3
