y = 4x + 11
3x - 2y = -7
The first equation is already solved for y, so replace
the y in the second equation by what y equals, namely,
(4x+11)
3x - 2y = -7
3x - 2(4x+11) = -7
3x - 8x - 22 = -7
-5x - 22 = -7
-5x = 15
x = -3
Now to find y, replace x by -3 in the first equation:
3x - 2y = -7
3(-3) - 2y = -7
-9 - 2y = -7
-2y = 2
y = -1
So the solution is (x, y) = (-3, -1)
