# CCSS.Math.Content.HSA.CED.A.3 - Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods.

1. Algebra review - Solve systems of linear equations
2. Represent Constraints - Students have already translated words into algebraic equations (sometimes with more than one variable!) and have actually taken the time to solve the problem. We hate to make you the villain here, but you have to tell them their work isn't over. Students now have to interpret the results. Page includes sample quiz with answers.
3. Systems of equations - Solve a system of equations using substitution: word problems
4. Systems of equations - Solve a system of equations using any method: word problems
5. Systems of equations: Elimination - Solve a system of equations using elimination: word problems
