Answer 2

what is the solution of the system? use elimination. 3x-4y=-24. x+y=-1?
--------------------------------------...
3x-4y=-24
x = -y-1

substitute

3(-y-1) -4y = -24

expand and combine terms

-3y -3 -4y = -24

add 3 to both sides

-7y = -21

y = 3

substituting this into x = -y-1, we have

x = -3-1, or x = -4

solution is (-4, 3).
