Multiply the 2nd equation by 4, making the coefficient on x in the 2nd equation the additive inverse of the coefficient on x in the first equation:
Add this to the 1st equation:
Notice that the x variable has been eliminated.
Solve for y
Substitute this value for y into either of the original equations; let's use equation 2:
 = 7)
The solution set is then \})
Check:
 - 3(-2) = -6)
Checks
 - 2(-4) = 7)
