    x=1

    Step-by-step explanation:

    7x - 20 = 2x - 3 (3x + 2)

    Distribute

    7x - 20 = 2x - 9x - 6

    Combine like terms

    7x-20 = -7x - 6

    Add 7x to each side

    7x+7x-20 = -7x+7x - 6

    14x - 20 = - 6

    Add 20 to each side

    14x-20+20 = -6+20

    14x = 14

    Divide by 14

    14x/14=14/14

    x=1
