2. 9/30/15 Lesson 2 – 1 Solutions of Equations Day 1 Advanced Math/Trig Ch 2 TEST on Tues 10/27

3. Learning Objective To find solutions of equations To be aware of extraneous solutions

4. 1. 3(2x – 1) – 2(3x + 4) = 11x 6x – 3 – 6x – 8 = 11x - 11 = 11x 11 11 x = – 1 {–1} Solve a Multi-Step Equation

6. 3. 6x + 5 – 2x = 4 + 4x + 1 4x + 5 = 4x + 5 - 5 - 5 4x = 4x -4x - 4x 0 = 0 ALWAYS TRUE!!! Infinite Solution!!{R} Solve a Multi-Step Equation

7. Solve a Rational Equation (y-1)(y-2) mult by common denom BUT, 2 makes denom = 0 So, NO SOLUTION 4.
