Combining Like Terms — Easy Worksheet 1
Grade 7 · Whoobee Name: ____________________ Date: __________
Simplify each expression. Write the variable terms first (x, then y), then the number.
How to solve
Like terms have the same variable part. Add or subtract their coefficients, keeping the sign in front of each term: 5x − 8 − 2x + 3 = (5 − 2)x + (−8 + 3) = 3x − 5. Numbers without a variable combine with each other.
Example
Simplify: 3 + 3x + 2x
Answer: 5x + 3

💡 Combine the x-terms: 3x + 3x = 6x. The number 2 has no like term, so it stays. So the answer is 6x + 2.
✓ Correct!
