    x=3

    y=11

    Step-by-step explanation:

    y = 3x + 2 equation 1

    y = 7x - 10 equation 2

    using equation 1 in equation 2 we have:

    3x + 2 = 7x - 10

    2=7x - 3x - 10

    2 = 4x - 10

    2+10 = 4x

    12 = 4x

    12/4 = x

    we have:

    x = 3

    using equation 1:

    y = 3x + 2

    y = 3 (3) + 2

    y=9+2

    y=11
