  1. Combining Like Terms Review

  2. To be like terms, the variable part is what has to be the same, not the numbers. Different types of variables are unlike terms. 4x 8x2 unlike

  3. Suppose we have: It could also be: This is the commutative property.

  4. Or: Commutative property again

  5. You Try! Simplify by Combining Like Terms

  6. 5x +3 4x - 1 6x – 1 9x 5x + 4 12x Perimeter Review 9x + 4x – 1 + 5x + 4 18x + 3 6x – 1 + 5x + 3 +12x 23x + 2 Write an expression in simplest form that will solve for the perimeter of each of the triangles.

  7. Solve the Equation 8z –4 –10z = –20 – 2z –4 = –20 +4 = +4 – 2z = –16 – 2 – 2 z = 8

  8. CHECK Rewrite the problem. Everywhere you see a z, put in an 8 8z - 10z - 4 = - 20 8 (8) - 10 (8) - 4 = -20 64 - 80 - 4 = - 20 - 16 - 4 = - 20 - 20 = - 20

  9. Combining Like Terms with Fractions 9 – 2 + +
