There are five sets of simplifying expressions worksheets:

- Simplify Expressions (Add, Subtract Like Terms)
- Simplify Expressions (Multiply, Divide)
- Simplify Expressions (Distributive Property)
- Simplify Expressions (Combine Like Terms)
- Simplify Expressions (Distributive Property & Combine Like Terms)

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.

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:

- Identify and combine like terms: Like terms have the same variables raised to the same powers.
- 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).
- 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
