    Use x for the unknown value.

    Multiply by three: 3x.

    Increase that value by 3: 3x + 3

    Write an equation: 3x + 3 = 20.

    Use the order of operations to solve.

    3x + 3 = 20

    3x = 17

    x = 17/3

    The unknown value would be 17/3.

    The number is 5.666667. You can redo the steps using these inverse operations: 20-3=17, then 17/3 to get 5.666667.
