Systems of Equations by Substitution Self-Checking Riddle Worksheet

This worksheet is way more fun than a traditional drill-and-kill worksheet. Students will practice graphing in slope-intercept form and solving systems of linear equations by substitution.

THIS WORKSHEET IS SELF-CHECKING. As students find answers in an answer bank, they will reveal the answer to a riddle. Students will know if they are on the right track.

There is space on each problem for students to graph the equations (when both are in slope-intercept form), solve the system by substitution, AND check their solution by plugging in to both equations.
