Students solve this puzzle by matching equations with their solutions.
In this puzzle, both positive and negative coefficients are used, and all equations have integer solutions.
If you'd prefer a puzzle that only uses positive coefficients, you might prefer this listing:

Included are two versions of the puzzle:
(1) the solution, which may also be printed and cut apart before giving to students; and
(2) a "mixed up" version of the puzzle, which you may distribute to students if you want them to cut the pieces apart themselves before solving!
The puzzle is sized to print on an 8.5x11 piece of paper, and each piece measures approximately 2.3 inches wide.
