Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 students learn how to simplify an algebraic expression by adding or subtracting like terms.

How to simplify an algebraic expression by adding or subtracting like terms?

There are three sets of simplifying algebraic expression worksheets.

• Simplify Expressions (Two Terms)
• Simplify Expressions (Three Terms)
• Simplify Expressions (Four Terms)

To simplify expressions involving addition and subtraction, follow these steps:

1. Identify and combine like terms: Like terms have the same variables raised to the same powers.
2. Maintain the Sign of the Coefficient: When combining like terms, be sure to maintain the sign of the coefficient (the number in front of the variable).
3. Combine Constants: Combine any constants (numbers without variables) in the expression.

Example: Simplify 5x - 3y - 2x + y + 9
Combine like terms with x: 5x - 2x = 3x
Combine like terms with y: - 3y + y = - 2y
Combine constants: 9
So, 5x - 3y - 2x + y + 9 simplifies to 3x - 2y + 9
