| ( | x | + | 302 | ) | ÷ | ( | x | + | 524 | ) | = | 59 |
| 方程两边同时乘以: | ( | x | + | 524 | ) |
| ( | x | + | 302 | ) | = | 59 | ( | x | + | 524 | ) |
| x | + | 302 | = | 59 | ( | x | + | 524 | ) |
| x | + | 302 | = | 59 | x | + | 59 | × | 524 |
| x | + | 302 | = | 59 | x | + | 30916 |
| x | − | 59 | x | = | 30916 | − | 302 |
| - | 58 | x | = | 30916 | − | 302 |
| - | 58 | x | = | 30614 |
| - | 30614 | = | 58 | x |
| 58 | x | = | - | 30614 |
| x | = | - | 30614 | ÷ | 58 |
| = | - | 30614 | × | 1 58 |
| = | - | 15307 | × | 1 29 |
