Free printable equation solver
Equation Solver is a letter-algebra puzzle: each letter stands for one integer, and that value stays the same in every equation. This medium sheet lists six equations in A, B, and C, from simple two-letter sums to multiples and a subtraction that ends at a negative. Upper-elementary and middle-school students who like number puzzles, plus parents reviewing pre-algebra, enjoy the mix of substitution and checking.
Solution page included
Peek at the solution
This free printable is a high-resolution PNG sized for a 6x9 inch page, with a matching solution that fills in A, B, and C. Download both files with no signup, then print and solve at the kitchen table or in class.
How to play
- Read the six equations; each letter is one integer used everywhere.
- Start with the three two-letter sums to pin down A, B, and C.
- Test those values in the longer equations so they all hold.
- Write the three integers in the boxes at the bottom.
- Compare with the solution page when you want to check.
Print at 100% scale on letter or A4 paper so the six equations and the A, B, C boxes stay large enough to write in.
Frequently asked questions
Where is the Equation Solver answer key?
The matching solution is a second printable image on this page. It repeats the six equations and fills the bottom boxes with the integers for A, B, and C. Download it with the puzzle if you want to check work, or keep it hidden until you have tried the system yourself.
Is this Equation Solver puzzle free to print?
Yes. The puzzle and solution download as PNG files at no cost, with no signup. You may print copies for personal use, tutoring, or a classroom warm-up whenever you need a ready-made algebra page.
Who is this Equation Solver sheet for?
It is a medium three-variable system, so it fits students who already add and subtract confidently and are ready to treat letters as unknown numbers. Many grade 5–8 students, homeschool pre-algebra lessons, and adults who like short logic-math puzzles will find it a satisfying one-page challenge.
How should I print the equations so they stay readable?
Open the high-resolution PNG and print at 100% scale on letter or A4 paper. Avoid fit-to-page shrinking so the operators, underlines, and answer boxes stay large enough to write in. Black ink on plain paper is enough; scratch working in the margin or on a second sheet.
