Question

Solve the following system of equations. Please show your work to receive full credit.
x - y = 19
2x + y = 2

Part 2:
Explain which method you chose to solve the system and why you felt it was the best choice.

Answer 1

-2(x-y=19)
2x+y=2

-2x+2y=-38
2x+ y= 2
___________
3y=-36
Y= -12

Then plug in y for on of the equations
2x+(-12)=2
2x=14
x=7

So you used the elimination method
