  1. Review Simplify Expressions Distributing and Combining Like Terms

  2. Combining Like Terms: Like Terms – same variable with same exponent Simplify When combining like terms, only use the coefficients. 6x + 2x = 6x + 2x = 8x Simplify 4x + 3y – 2x + 4y = 2x + 7y Never, NEVER, combine x’s and y’s or constant terms with variable terms. 2x + 7y ≠ 9xy and 3a + 6 ≠ 9a.

  3. We are going to go around to each student and have them answer the problem. EVERYONE DO THE WORK AT YOUR DESK AS WELL.
