solution. inverse operations. Remember. hat makes the equation true. To solve a one-step addition equation, perform inverse operations to both sides of the equ. Practice. Use a bar model to solve each equation. 1. x 1 7 5 15 . 3. 14.5 5 6 1 y. 2. 19 5 x 1 13. 4. a 1 __ 1. 2 5 4 __ 3. 4 . Solve each equation. Check each solution.
Essential Ideas. • A one-step equation is an equation that can be solved using only one operation. • A solution to an equation is any value for a variable that makes the equation true. • To solve an equation, you must isolate the variable by performing inverse operations.
The document introduces bar models as a visual tool to represent and solve one-step addition equations, where bars are used to depict quantities and breaking the bars into parts shows the relationships between values; worked examples demonstrate using bar models to reason through equations and determine solutions as well as an alternative ...
