Objective
I can solve one-variable equations using inverse operations.
Part 1 of 3
Key concepts
3 concepts
- 1
When solving equations, it's helpful to imagine a balanced scale, where you must do the same operation to both sides to keep it balanced.
- 2
Inverse operations are operations that undo each other, such as addition and subtraction, or multiplication and division.
- 3
To solve the equation 2x + 3 = 9, you would first subtract 3 from both sides, then divide both sides by 2, resulting in x = 3.
