Combining Like Terms and Distributive Property Equations Review

3x + 5 + 2x - 7

• 5x + 2

• 5x - 2

• 5x + 12

• 1x - 2

Rewrite the expression by combining like terms.
3x² + y + 2y² + 4y²

• 3x² + 3xy + 6y

• 6y² + 2xy + 2x

What has to be done BEFORE you start solving a basic two-step equation?

• distributive property, combining like terms, and getting the variables all on one side

• distibutive property, move the variables to one side, cimbine like terms

• distributive property, cancel the constants, get variables to one side

• distributive property, combine like terms, eliminate the constant
