How would 2,-2 be a solution to the system of inequalities

2, -2 would be a solution to a system of inequalities if when substituted both of the inequalities are true. 
Example: 2x - 6 = y
                3x - 8 = y

1. Substitute
                2(2) - 6 = -2
                3(2) - 8 = -2

2. Solve
                4 - 6 = -2
                6 - 8 = -2

                Both of these equations are true. Which makes 2, -2 a solution.
