Here are some tips and tricks to help you effectively combine like terms: Identify like terms: Like terms are terms that have the same variables raised to the same exponents. Group like terms: To combine like terms, group them together. Add or subtract coefficients: Once you've grouped like terms together, simply add or subtract the coefficients (the numbers in front of the variables) to combine them.

To combine like terms, we can color coordinate the x-terms, y-terms, and z-terms and then combine them together group by group as follows: x-terms: 3x + 5x = 8x y-terms: 2y + 7y = 9y z-terms: -3z + z = -2z
