In the seven-step Problem Solving Strategy for Systems of Linear Equations, what is Step 4?
ASolve the system of equations
BTranslate into a system of equations
CName what we are looking for
DCheck the answer in the problem
Answer & Solution
Correct answer: B. Translate into a system of equations
1. Step 3 names what we are looking for by choosing variables to represent the quantities.
2. Step 4 then translates the problem's words into a system of equations using those variables.
3. Solving the system is Step 5, and checking the answer is Step 6, both of which come after the translation step.
