    You need to use all of them until you find the answer so lets fo this!

    a. (-10,-12) x=-10 y=-12

    3x+2y=6

    3 * (-10) + 2 * (-12) = 6

    -30-24=6

    -54=6

    This is incorrect, now we try the othe options

    b. (10,12) x=10 y=12

    3x+2y=6

    3*10+2*12=6

    30+24=6

    54=6

    This is incorrect then we try the other option

    c. (-10,12) x=-10 y=12

    3x+2y=6

    3 * (-10) + 2*12=6

    -30+24=6

    6=6

    And this is the correct answer. So the answer is c. (-10,12)

    3 (-10) + 2 (-12) = - 54 That's not right!

    3 (10) + 2 (12) = 54 That's also not right

    3 (-10) + 2 (12) = - 6 Close but not right

    3 (10) + 2 (-12) = 6 is the correct answer
