    -7x + 2y = 0

    6x + 6y = 0

    ordered pair: (-2,2)

    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.

    -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.
