    You need one of the variable in the equations to be equal (or a negative version of the other) So that when you add or subtract one equation from the other, that variable is eliminated.

    So equations: (1) 5x-9y=-16 (2) 2x+6y=-16 We can make them both have 10 as their x coefficients (1) 2*(5x-9y=-16) (2) 5*(2x+6y=-16) simplify (1)10x - 18y = - 32 (2)10x + 30y =-80 Equation 1 minus equation 2: -48y = 48 y=-1
