Homework Review Workbook pp. 49 – 50 Reflect 1a. No, you can simplify the right side of the equation by subtracting 18 – 7 = 11 Reflect 2a. Yes, you could divide both sides by 2 and get x – 6 = -9 which has the same solution, x = -3. It makes sense to do this whenever the number being distributed divides evenly into all other terms. It does not make sense if the number being distributed does not divide evenly inot all the other terms as this will lead to fractions appearingin the equation. Practice 1: Distributive property; Subtraction Property of Equality; Inverse Property of Addition; Simplify; Division Property of Equality; Simplify. Practice 2: Subtraction Property of Equality; Mult Prop of Equality Practice 3: Distributive Property; Subtraction Property of Equality; Division Property of Equality

What are Literal Equation? Literal equations are equations involving two or more variables. They are solved using inverse operations and properties of equality just as other algebraic equations are solved.

Example: One-Step Literal Equations Solve for A: Solve for Z: AX = C Y + Z = -8 Solve for H: Solve for R V = LWH C = 2R

Two-Step Literal Equations: Solve for Y: Solve for L: 7X + 14Y = -21 P = 2W + 2L Solve for B: Solve for Y: 5A + 9 = 2A – 3B 3X – 4Y = 10X + 14Z LecturePLUS Timberlake
