-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.
