Not yet Getting there Solid 2 DEFINE YOUR VARIABLES FIRST You need: Paper, Word problems from real situations Always start by writing what each variable stands for, in words, with units. Write one equation per constraint in the problem — usually a count and a total. Choose the method: substitution when a variable is already isolated, elimination otherwise. Check both equations with the answer, not just one. Sanity check against the story: can you sell −20 tickets? SAY THIS WHEN IT STALLS "Write down what x actually is, in words, with units. Half the errors die right there." Two-equation problems with the variables defined for them. Mixture and rate problems, and systems of inequalities with a feasible region.
