x = 5.

Explanation:

We start with:
3x - 36 = -21.

To solve for x, we have to leave it alone. Step-by-Step:
We first pass the -36 to the other side, adding:
3x = -21 +36,
3x = 15.
We now divide by 3 on the right, as on the left it is multiplying:
x = 15/3,
x = 5. This is the final answer.

Hope it Helps! :D .
