Combining like terms
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- two x-terms: 3x + 4x
- three x-terms, minus in the middle: 7x − 3x + 2x
- two x-terms and a constant: 3x + 4 + 2x
- two different letters: 3x + 2y + 5x − y
- an xy-term beside x and y: 3xy + x + y + 5xy
- x² and x in one expression: x² + 3x + 2x²
Sample Sheet · Level 1

Sample Sheet · Level 3
- 5x + x =
- 7x − 10x + x + 5 =
- 1 + 3x + x =
- 9x − 4y + 6x =
- 3x² + 6x + 4 − 4x² =
- −2x + 9xy − 2y + 1 − 4xy =
- 7xy + 5x − 2y + 2xy =
- 3x² − 3x − 2x² =
Answer key
