If 4=3x+16, find the value of x-7 (show work)

-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.
