    BC = 9

    Step-by-step explanation:

    Assuming this is a straight line

    AB + BC = AC

    2x-6 + x+2 = 17

    Combine like terms

    3x - 4 = 17

    Add 4 to each side

    3x-4+4 = 17+4

    3x = 21

    Divide each side by 3

    3x/3 = 21/3

    x = 7

    We want to find BC

    BC = x+2

    =7+2

    =9
