| 方程右边 = | 77 | x | + | 77 | × | 37 10 |
| = | 77 | x | + | 2849 10 |
943 5 | + | 637 5 | x | = | 77 | x | + | 2849 10 |
637 5 | x | − | 77 | x | = | 2849 10 | − | 943 5 |
252 5 | x | = | 2849 10 | − | 943 5 |
252 5 | x | = | 963 10 |
| x | = | 963 10 | ÷ | 252 5 |
| = | 963 10 | × | 5 252 |
| = | 107 2 | × | 1 28 |
