x = 2, and y = 0. Here's one way to solve:
Multiply the second equation (both sides) by 3, then add the two equations:
8x + 6y = 16
12x - 6y = 24
----------
20x = 40 ----> x = 2, then substitute x=2 into one of the original equations:
8*2 + 6y = 16 --> 6y = 0, and y=0. Check with the other equation: 4*2 - 2y = 8 ---> -2y = 0, and y = 0.
