Answer 2

y = 1
x = -1

Answer 3

If you multiply the second equation by -1, then the x's would cancel out. Using elimination, you would add what is left, so 8y = 8, and y = 1. Substitute 1 into the first equation, which would give you 4x + 7 = 3. Use inverse operations to solve. 4x = -4, x = 1. So, your answer would be (1, -1)
