You can put this solution on YOUR website! I need to use any method to solve: = -4
x + y = -2
:
Multiply the 1st equation by 4, resulting in
2x - y = -16
x + y = -2
----------------adding eliminates y, find x
3x = -18
x =
x = -6
Find y
x + y = -2
-6 + y = -2
y = -2 + 6
y = 4

Check solutions, in the 1st original equation = -4 = -4 - 1 = -4
-3 - 1 = -4
