You can solve inequalities using the same steps that you would use to solve for a variable in a normal equation. The only difference is that you would flip which way the inequality sign (< or >) faces if you divide by a negative number while solving. Here, you would subtract 7 from both sides to get 3x>21. Then, divide both sides to get x>7 as your answer.
