    x≈ - 4.71

    Step-by-step explanation:

    7 (x+6) = 9

    Distribute the 7 into the parenthesis.

    7x + 7 (6) = 9

    Multiply the numbers.

    7x + 42 = 9

    Subtract from both sides.

    7x+42 = 9

    -42 - 42

    Now, divide to both sides.

    7x = - 33

    7 7

    x = - 4.71428571429

    x≈ - 4.71
