| ( | m | ÷ | 2 | ) | + | 40 | ÷ | 96 | × | 88 | + | ( | m | ÷ | 2 | ) | + | 40 | = | m |
| Left side of the equation = | ( | m | ÷ | 2 | ) | + | 110 3 | + | ( | m | ÷ | 2 | ) | + | 40 |
| = | ( | m | ÷ | 2 | ) | + | 230 3 | + | ( | m | ÷ | 2 | ) |
| ( | m | ÷ | 2 | ) | + | 230 3 | + | ( | m | ÷ | 2 | ) | = | m |
| Left side of the equation = | m | ÷ | 2 | + | 230 3 | + | ( | m | ÷ | 2 | ) |
| = | 1 2 | m | + | 230 3 | + | m | ÷ | 2 |
| = | 1 | m | + | 230 3 |
| 1 | m | + | 230 3 | = | m |
| 1 | m | − | m | = | - | 230 3 |
| 0 | m | = | - | 230 3 |
