    The answer to your question is below

    Step-by-step explanation:

    First way

    20 = 5 (-3 + x) expand

    20 = - 15 + 5x simplify like terms

    5x = 20 + 15

    5x = 35 divide both sides by 5

    5x/5 = 35/5

    x = 7

    Second way

    20/5 = 5/5 (-3 + x) Divide both sides by 5

    4 = - 3 + x Add + 3 in both sides

    4 + 3 = - 3 + 3 + x Simplify like terms

    7 = x
