  1. No.

    You need to subtract 7 from both sides of the equation.

    Please try again.

  3. You're closer, but still wrong.

    Check your division.

  4. 2x+7=79

    2 x + 7 - 7 = 79 - 7

    2 x + 0 = 72

    2 x/2 = 72/2

    x = 72/2

    72 inches is six feet so half of that is three feet which is 36 inches :)
