The Golden Rule of Equations
Think of an equation like a perfectly balanced scale. Whatever you do to one side, you MUST do to the other side to keep it balanced. Want to remove the +7? Subtract 7 from BOTH sides. Want to get rid of the "times 3"? Divide BOTH sides by 3. The goal: get x completely alone on one side.
