| - | ( | 4 | − | 3 | m | ÷ | 1 | ) | = | 8 | ÷ | 5 | − | m |
| Left side of the equation = | - | 4 | + | 3 | m | ÷ | 1 |
| = | - | 4 | + | 3 | m |
| - | 4 | + | 3 | m | = | 8 | ÷ | 5 | − | m |
| Right side of the equation = | 8 5 | − | m |
| - | 4 | + | 3 | m | = | 8 5 | − | m |
| 3 | m | + | m | = | 8 5 | + | 4 |
| 4 | m | = | 8 5 | + | 4 |
| 4 | m | = | 28 5 |
| m | = | 28 5 | ÷ | 4 |
| = | 28 5 | × | 1 4 |
| = | 7 5 | × | 1 |
| m | = | 7 5 |
| m | = | 1.4 |
