Well first you would decide on which equation you want to use, then you would choose a variable to solve for. And then solve for that variable in the equation you choose. Then once you get that answer you would then plug in that answer you just got into the other equation you haven't used yet. and just solve. Just remmeber PEMDAS- Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
