Introduction: Turning Words into Math
Word problems are a common part of math tests, and many of them require using a system of two or more equations to find the solution. While word problems can sometimes feel overwhelming, they become much easier when you follow a step-by-step process to translate the words into mathematical equations.
The hardest part for many students isn't solving the equations—it's setting them up correctly from the word problem. Once you have the equations, you can use methods like substitution or elimination to find your answer.
Step-by-Step Process for Word Problems
Step 1: Identify the Variables
Read the problem carefully and determine what you're being asked to find. These unknown quantities become your variables. Choose letters that make sense (like C for cheese pizzas, T for tickets, etc.).
