Which is the most efficient way to solve this equation?

x−57=135

A. Do nothing because the equation is already solved.

B. Subtract 135 from both sides of the equation so all terms will be on the same side of the equal sign.

C. Subtract 57 from 135 because x equals 78.

D. Add 57 to both sides of the equation because addition is the inverse operation of subtraction.

The Answer is D.

Step-by-step explanation: You are trying to get x by itself, and in order to do that, you need to get the 57 away from it. In order to do THAT, you need to do the opposite of what s already being done. Since your already subtracting it, in order to get it away from x, you need to add it to itself, and then add it to the other side, because what you do to one side, you do to one side, you must do to the other.
