Answer 3

the first one is not a proper system of equations.. by definition if x+y = -5 and x+y = 6 then -5 should equal 6 which it does not. It is not solveable. The second you can just just use substition.
solve for y in the first which yields: 3x+4y = 2 -> y = -(3/2)x + 1/2 and sub it in for y in the second equation and solve for x then go back and solve for y.
