Lesson 5 Algebra CC Mr. Jones Name________________________ Date_______________________ S.W.B. A.T: Solving Equations in One Variable. DO NOW: Cynthia solved the following equation. Write down the steps or the property that she used to solve the equation. Is her solution correct? ________________________________________ ________________________________________ ________________________________________ ________________________________________ Skills: Adding/Subtracting like terms Example 1: Solve each equation for the variable. a. 9x – 3 = 2x + 46 Distributive Property b. 7x – 4 = -2x + 9 + 7x – 5 Exercise 1: Solve each of the following equations. a) b) 10 – x – 3x = 7x – 23 y + 30 = 12y – 14 c) 10 – 4x = -7x + 12 d) – 2(n – 4) = -2(n + 2) EXIT: Solve the equation. 5x – (2x + 2) = x + (3x + 5) Lesson 5 Algebra CC Mr. Jones 1. 5 –x – 2 = 3 + 4x + 5 2. 3(x – 7) – (5x – 11) = 14 3. 2(x – 3) – 17 = 13 – 3(x + 2) Name________________________ Date_______________________ 4. 3(x – 2) + 7 =2(x + 2) 5. 8n – 4n = 14 – 8n 6. -5 + 3(a + 5) = 2(3a – 4)
