Solve and Write Multiplication Equations Objective: To successfully solve and write multiplication equations. Solve and Write Multiplication Equations A coefficient is the numerical factor of a term that contains a variable. e.g. 3x = 9 The coefficient is 3 Solve and Write Multiplication Equations What is the coefficient? 7y = 49 Solve and Write Multiplication Equations What is the coefficient? 7y = 49 Solve and Write Multiplication Equations What is the coefficient? 8h = 32 Solve and Write Multiplication Equations What is the coefficient? 8h = 32 Solve and Write Multiplication Equations What is the coefficient? 45 = 3g + 6 Solve and Write Multiplication Equations What is the coefficient? 45 = 3g + 6 Solve and Write Multiplication Equations What is the coefficient? 5 – 6b = 6 Solve and Write Multiplication Equations What is the coefficient? 5 – 6b = 6 Solve and Write Multiplication Equations An equation is only true if both sides are equal. A teeter totter will only be balanced if there is equal weight on both sides. Solve and Write Multiplication Equations Multiplication and Division Property of Equality states if two expressions are equal to each other and the exact same number is multiplied or divided from both sides, the two sides will remain equal. Solve and Write Multiplication Equations Solve. 2b = 10 To Solve an Algebraic Equation. Step 1 – Determine the coefficient. What is the coefficient? Solve and Write Multiplication Equations Solve. 2b = 10 To Solve an Algebraic Equation. Step 1 – Determine the coefficient. Solve and Write Multiplication Equations Solve. 2b = 10 To Solve an Algebraic Equation. Step 2 – Multiply both sides by the reciprocal of the coefficient. What is the reciprocal of the coefficient? Solve and Write Multiplication Equations Solve. 1 2b = 10 1 2 2 To Solve an Algebraic Equation. Step 2 – Multiply both sides by the reciprocal of the coefficient.
