Let's first rewrite it as a multiple of each to get the x's able to cancel one another out.

  1 [(2x) + (y) = (-1)]
  2 [(-x) + (3y) = (18)]

  2x + y = -1
-2x + 6y = 36

This allows us to add them,

    (2x + y = -1)
+ (-2x + 6y = 36)
_______________
  0x + 7y = 35

Solving for y,

         y = 5

Then plug in 5 for y in one of the equations and solve for x.
