    -11

    Step-by-step explanation:

    First get x alone.

    Subtract 16 from both sides: - 12 = 3x

    Divide both sides by 3: - 4 = x

    Plug in x: - 4 - 7 = - 11

    4=3x+16

    4-16 = - 12

    -12=3x

    We then divide the - 12 by 3 and the 3x by 3. - 12 divided by 3 is - 4.

    -4 minus 7 (or - 4-7) equals - 11.

    The final equation is - 4-7=-11

    The final answer is - 11.
