| ( | ( | m | + | 3 | ) | ÷ | 6 | ) | = | 1 | − | ( | ( | 3 | − | 2 | m | ) | ÷ | 4 | ) |
| 方程左边 = | ( | m | + | 3 | ) | ÷ | 6 |
| = | m | × | 1 6 | + | 3 | × | 1 6 |
| = | m | × | 1 6 | + | 1 2 |
1 6 | m | + | 1 2 | = | 1 | − | ( | ( | 3 | − | 2 | m | ) | ÷ | 4 | ) |
| 方程右边 = | 1 | − | ( | 3 | − | 2 | m | ) | ÷ | 4 |
| = | 1 | − | 3 | × | 1 4 | + | 2 | m | × | 1 4 |
| = | 1 | − | 3 4 | + | 1 2 | m |
| = | 1 4 | + | 1 2 | m |
1 6 | m | + | 1 2 | = | 1 4 | + | 1 2 | m |
1 6 | m | − | 1 2 | m | = | 1 4 | − | 1 2 |
| - | 1 3 | m | = | 1 4 | − | 1 2 |
| - | 1 3 | m | = | - | 1 4 |
1 4 | = | 1 3 | m |
1 3 | m | = | 1 4 |
| m | = | 1 4 | ÷ | 1 3 |
| = | 1 4 | × | 3 |
| m | = | 3 4 |
| m | = | 0.75 |
