Answer:

-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.
