Solving rac{2}{3}(3m - 6) = 5 - m Using a General Strategy
To solve the linear equation rac{2}{3}(3m - 6) = 5 - m, apply the general five-step strategy:
Step 1. Simplify both sides. Distribute the rac{2}{3} into the parentheses on the left side. The product of rac{2}{3} and simplifies to , and rac{2}{3} times simplifies to :
Step 2. Collect all variable terms on one side. Add to both sides to bring the variables to the left side:
Step 3. Collect all constant terms on the other side. Add to both sides to bring the constants to the right side:
Step 4. Make the coefficient of the variable term equal to 1. Divide both sides by : rac{3m}{3} = rac{9}{3}
Step 5. Check the solution. Substitute for in the original equation: rac{2}{3}(3(3) - 6) = 5 - 3 rac{2}{3}(9 - 6) = 2 rac{2}{3}(3) = 2
Since the equation balances, the solution is correct.
