1. The elimination method removes one __ by combining equations.
2. Which method is often efficient when coefficients are opposites?
3. Match the case to the result: the same line written two ways
Match with:
Answer:
4. If 2x + y = 11 and x - y = 1, adding the equations eliminates __.
5. Why is elimination a valid method?
6. Which statement best fits equation modeling?
7. When an ordered pair makes both equations true, it is the __ to the system.
8. Why should students interpret the final answer in words?
📋 Teacher Answer Key
1. variable
2. elimination
3. infinitely many solutions
4. y
5. Combining equivalent equations preserves the same relationships while removing one variable to simplify the system
6. Variables should be defined and interpreted in context.
7. solution
8. The numbers must be connected back to the real situation so the solution has meaning and can guide a decision

Write, simplify, and solve equations and inequalities to model real situations with rational numbers and multi-step reasoning.

Build BackgroundGrade 7
➕Operations with Rational Numbers

Add, subtract, multiply, and divide rational numbers with meaning, using signs, opposites, and real-world contexts instead of memorized sign tricks alone.
