Final answer:

To solve the equation X - 21 = 12, we add 21 to both sides and find that X equals 33.

Step-by-step explanation:

The equation given is X - 21 = 12. To find the value of X, we need to isolate X on one side of the equation. This can be done by adding 21 to both sides of the equation, which gives us:

X - 21 + 21 = 12 + 21

So, X = 33.

Therefore, the value of X that satisfies the equation is 33, which corresponds to option (c).
