    Hello

    We have two equations and need to find x and y

    (1) 6x+7y=-46

    (2) 3x-2y=32

    multiply (2) by 2 it gives

    (2') 6x-4y=64

    (1) - (2') gives

    6x+7y-6x+4y=-46-64 = - 110

    so 11y = - 110

    y = - 10

    replace in (2) it gives

    3x+20=32

    3x=12

    x = 12/3 = 4

    the solution is (4,-10)

    do not hesitate if you need further explanation
