Study Guide For 2 Step Equations

  1. 1. Name __________________________________________ Date ____________ Polizzi/Woska Math – 6 Study Guide Math Test Two-Step Equations Solving Equations A two-step equation is an equation that contains two operations. Example 1: 2y + 3 = 11 Step 1: 2y + 3 – 3 = 11 – 3 (Subtract 3 from both sides to undo the addition.) 2y = 8 Step 2: 2y = 8 (Divide each side by 2 to undo the multiplication.) 2 2 y=4 Example 2: 2b – 18 = 34 Step 1: 2b – 18 + 18 = 34 + 18 (Add 18 to each side.) 2b = 52 Step 2: 2b = 52 (Divide each side by 2.) 2 2 b = 26 Example 3: x + 5 = 10 2 x Step 1: + 5 – 5 = 10 – 5 (Subtract 5 from each side.) 2 x =5 2 x Step 2: (2) = 5 (2) (Multiply each side by 2.) 2 x = 10 Example 4: x -3=2 4 x Step 1: - 3 + 3 = 2 + 3 (Add 3 to each side.) 4 x =5 4 x Step 2: (4) = 5 (4) (Multiply each side by 4.) 4 x = 20
