Advanced Algebra - Trigonometry Objective: SWBAT solve linear equations. 1

2
Warm Up Simplify: 1.8b - 3( 4 – b ) 2.-6 (m – 9) + 14m – 20 3.2 (b + 5) + 3 (2b – 10) 4.-w 3 + w 2 - 7 w 2 - 8 w 3 5.7t (t 2 + 2) + 9t (t – 2) 2

3
Vocabulary Equation: a statement that two expressions are equal. Ex. x + 2 = 9, x 2 – 4x +10 = 0, Solution: all numbers that make an equation true. Solution Set: the set of all the solutions of an or condition. Equivalent Equations: equations with the same solution set Ex. x + 1 = 5 and 6x + 3 = 27 Linear Equation: a linear equation in one variable has the form ax + b = c (aka first degree equation) 3

4
Which of the following are a linear equations? 4

5
Solve an equation with variable on one side. 5

6
Solve an equation with variable on both sides. 6 Solve: 8y – 16 = 13y + 9

7
