| X | ÷ | ( | 7 10 | + | X | ) | = | 97 | ÷ | 24 |
| 方程两边同时乘以: | ( | 7 10 | + | X | ) |
| X | = | 97 | ÷ | 24 | × | ( | 7 10 | + | X | ) |
| X | = | 97 | ÷ | 24 | × | 7 10 | + | 97 | ÷ | 24 | × | X |
| X | = | 679 240 | + | 97 24 | X |
| X | − | 97 24 | X | = | 679 240 |
| - | 73 24 | X | = | 679 240 |
| - | 679 240 | = | 73 24 | X |
73 24 | X | = | - | 679 240 |
| X | = | - | 679 240 | ÷ | 73 24 |
| = | - | 679 240 | × | 24 73 |
| = | - | 679 10 | × | 1 73 |
| X | = | - | 679 730 |
| X | = | - 0.930137 |
