So what we do to one side of the equal sign, we must do to the other side as well.
We want to solve for f, so we need to subtract 15 on both sides of the equal sign in order to get f alone by itself on the left side:
So now we know that f = 20.
Solve for x and draw a number line. 3x−91>−87 AND 17x−16>18
