    For the first one the answer is y=-1x+6 which means x=-1 and y=6

    x = 4.625, y = 1.375

    Step-by-step explanation:

    I am assuming that the second equation is 4x - 4y = 13.

    2x+2y=12

    4x-4y=13

    Multiply first equation by - 2:-

    -4x - 4y = - 24 Add this to the second equation to eliminate x:-

    -8y = - 11

    y = 11/8 = 1.375

    Plugging this into the first equation:-

    2x + 2 (1.375) = 12

    2x = 9.25

    x = 4.625
