AZ:
The first step in solving equations is trying to get that variable, that letter `x`, all by itself. \( 1331x^3 - 216 = 0\) We would have to follow PEMDAS but in reverse. That means we first take care of the addition/subtraction and then move to multiplication/division. We're subtracting 216. To move it to the other side, we have to do the opposite of that. What do you get when you add 216 to both sides?
