    A) 5x - 2y = 12

    B) 3x + 2y = 36 Adding both equations eliminates "y"

    8x = 48

    x = 6 Putting x=6 into equation B we get

    3*6 + 2y = 36

    2y = 18

    y = 9

    5x-2y=12 eq1

    3x+2y=36 eq2

    8x=48

    x=6

    X iS 6

    substitute X S6 in equation 2

    3 into 6 + 2 Y is equal to 36

    18 + 2 Y is equal to 36

    Y is equal to 9
