About this worksheet

What students practice

Students solve systems of two linear equations using substitution and elimination.
Students identify simple systems with one solution, no solution, or infinitely many solutions by inspection.
Students graph linear equations and estimate the solution of a system.

How to use

Use after introducing systems of equations. Have students show algebra on separate paper and compare graphical estimates with exact solutions.

Coding Camp: Project Progress Checks

Use inspection, algebra, and graphs to solve systems.

Inspect the Progress Checks

The camp's tracking tool uses pairs of equations. Inspect each system before doing lengthy calculations. Variables are defined separately in each problem.

A project has x finished tasks and y unfinished tasks. Which ordered pair (x, y) satisfies both equations?
x + y = 9
x − y = 1
