Question 679262
-5x + y = -2
-3x +6y = -12
...
y = -2 + 5x
Substitute into the second equation for the "y"
...
-3x + 6(-2+5x) = -12
Distribute the 6
-3x - 12 + 30x = -12
27x - 12 = -12
27x = 0
x = 0
...
Plug the x into either equation and solve for y
y = -2 + 5(0) = -2
...
x = 0
y = -2
...
Check
-5(0) + -2 = -2 : Correct
-3(0) + 6(-2) = -12 : Correct
