22 - 4 = 18
• 18 + 18 + 18 + 18 = 72
4 × 18 = 72
• 18 + 4 = 22

To find the total number of tubes of paint the teacher bought, you can use the following equations:
1. **4 × 18 = 72** (This represents multiplying the number of packs by the number of tubes in each pack, which gives the total number of tubes.)
2. **18 + 18 + 18 + 18 = 72** (This represents adding the number of tubes in each of the 4 packs together to find the total, which also gives 72.)
So, the two correct equations are:
- **18 + 18 + 18 + 18 = 72**
- **4 × 18 = 72**
The other equations do not correctly represent the total number of tubes of paint purchased.
