the way to figure out if that ordered pair is a solution is pretty simple, you just plug the ordered pair into both equations, and check if the outcome is true.
</span>-7(-2) + 2(2) = 0 14 + 4 = 0 18 = 0 is NOT true, so this isn't a solution. still, check your second equation as well.
6x + 6y = 0 6(-2) + 6(2) = 0 -12 + 12 = 0
for this equation, it is a solution. however, because the solution must apply to the system as a whole, and not just one of the equations, the ordered pair still is not a solution.
