Honor's PreAlgebra Solving Equations with Grouping Symbols (chapter 82) Solving Equations with Grouping Symbols (Honor’s PreAlgebra) Solve each equation. Show your work. 1. 3(g ‐ 3) = 6 Steps: 1. Use the distributive property to eliminate any parentheses. 2. Move the variables to one side of the equation 3. Move the numbers to the other side of the equation. 4. Solve the equation 2. 2(a ‐ 2) = 3(a ‐ 5) Remember: When solving an equation: • If the left solution and the right solution are the same (x = x) or (5 = 5), the answer is all solutions. 3. 3(2g + 4) = 6(g + 2) • If the left solution and the right solution are different (5 = 0, -3 = 2), the answer is ∅ (null). 5. Check (by plugging in the answer). 1 Honor's PreAlgebra Solving Equations with Grouping Symbols (chapter 82) Solving Equations with Grouping Symbols (Honor’s PreAlgebra) Solve each equation.
