Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6(4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

Equivalent Expressions

How can you identify equivalent algebraic expressions?

1. Multiply the outside with the 1st number.

2. Multiply the outside with the 2nd number.

3. Put the two together and add the operation from the parenthesis.

• They have the same value. 

• You can check if they are equal by substituting X with a number.

Let's Compare Another Way!

• Simplify each expression by combining like terms.

• Compare the simplified expressions.
