SOLVING LINEAR EQUATIONS, INEQUALITIES AND ABSOLUTE VALUES Multi-Step Equations Solve each equation. Check your solution. 1) 4x – 12 = -3x + 92) x – 8 = -33) 6(-x – 5) = -4(x – 3) – x 4) 3 – (2x + 9) = 175) Find the dimensions of the 20x - 48 rectangle, given the area is 7 504 square units

3
Solving Inequalities Inequality symbols: Greater Than > and Less Than < Multiplying / dividing by a negative number FLIP the inequality sign OPEN circle when graphing / ≥, ≤ CLOSED circle when graphing Solve each of the following and graph the solution on the number line. 1) -3x + 9 < 122) 7x – 10 ≥ 113) x – 4 ≤ 84) -4 < 2x – 6 ≤ 8 5) -3x + 5 < -1 or 4x – 1 ≤ 3

4
Solving Absolute Value Equations Isolate the bar term on one side of the equal sign Set up TWO equations – one the same without the bars, the other the opposite of what is inside the bars Solve each equation Solve each of the following: 1) 2) 3) 4)
