Texas Algebra I, Lesson 7: Simplifying Algebraic Expressions
Mrs. Young

2. Lesson Objectives: Define “like terms”
Identify like terms in a given algebraic expression or equation
Simplify expressions/equations by combining like terms

3. Like terms- Like terms are terms that contain the same variables raised to the same power.
examples
Counterexamples
(non-examples)
4x, 3x
9, 13
14xyz, xyz
4, 3x
5g, 2g2
23xyz, 2xy

4. Guided Practice: expressions
3x + 4b –x
3y -5xy +17 –y + (-4xyz)
2x2 +3x x + 5x2

5. Guided Practice: equations
Directions: Simplify.
2x – 3y = 7x + y – 5
6jkl + 4j – 8klj = 21j – 102
21θ – 32 = 45 – θ + 3θ2
