Learning Objective
I can solve two-step equations using inverse operations.
- 1
When solving two-step equations, you must 'undo' two operations to get the variable all by itself.
- 2
To solve two-step equations, use the order of operations in reverse, which means you undo addition and subtraction before multiplication and division.
- 3
When an equation has a fraction line, the expressions above and below the line are treated as an 'implied' group, so you undo operations inside the group last.
