-3x + 6y + 5 = -7
      -5 -5
      -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
6y = -12 + 3x
6    6
y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3x + 3x - 12 = -12
0x - 12 = -12
   +12   +12
   0x = 0
      0   0
   x = 0
-3(0) + 6y = -12
0 + 6y = -12
+0    +0
      6y = -12
   6    6
      y = -2
(x, y) = (0, -2)
