Will give brainliest - even if you just do step one 1. define two different variables for your problems. 2. write two algebra equations or inequalities using the information given in your word problem. both of your equations or inequalities must contain both variables 3. using your two equations or inequalities, solve your problem twice for both variables. once using the addition/elimination method and a second time using the substitution method showing all algebra work with both methods. 4. check your solutions with both of your equations or inequalities showing all algebra work for both checks. 5. explain why it is important to always check all solutions with both equations for a system of equations problem.
