Question 88462
-3x+7y=2
x+2y=-18
----------
Multiply thru the 2nd equation by 3 to get:
3x+6y=-54
Add that to the 1st equation to get rid of the x terms:
13y = -52
y = -4
----------
Substitute that value of y into x+2y=18 to solve for x:
x - 8 = -18
x = -10
---------------
Check the answers in -3x+7y=2
30-28=2
2 = 2
