1. Starter! Write down the equation which results when:
2 is subtracted from both sides of 2 – 2x = -4
Both sides of -2(4x – 1) = -8 are divided by -2
Both sides of 9x – 3 = are multiplied by 4 4
WWK:
Inverse operations – opposite operations (eg. addition and subtraction are inverse operations)

5. Inverse Operations Addition and subtraction are inverse operations.
Example 1 - What is the inverse of:
- 6?
+ 13?
x 15?
÷8?
Addition and subtraction are inverse operations.
Multiplication and division are inverse operations.
