4 m
Find the value of 1 unit.

- 5 u + 8 = 1 u + 20
- 1 u + 20 = 5 u + 8
- 5 u - 20 = 1 u + 4
- 1 u + 4 = 5 u - 20

Level 2

Find the value of 1 unit.

4 m
Find the value of 1 unit.

- 1 u + 8 = 20 - 5 u
- 20 - 5 u = 1 u + 8
- 1 u - 10 = 20 - 5 u
- 20 - 5 u = 1 u - 10

Level 2

Find the value of 1 unit.

4 m
Find the value of 1 unit.

- 5 u - 20 = 1 u - 8
- 1 u - 8 = 5 u - 20

- 6 u - 15 = 1 - 2 u
- 1 - 2 u = 6 u - 15
- 5 u - 2 = 14 - 3 u
- 14 - 3 u = 5 u - 2

Level 2

Find the value of 1 unit.

4 m
Find the value of 1 unit.

- 7 u - 20 = 4 u + 10
- 4 u + 10 = 7 u - 20
