| ( | x | − | 4 | ) | ÷ | 76 100 | + | 4 | = | x | ÷ | 7 | ÷ | 6 |
| 方程左边 = | x | × | 100 76 | − | 4 | × | 100 76 | + | 4 |
| = | x | × | 100 76 | − | 100 19 | + | 4 |
| = | 100 76 | x | − | 24 19 |
100 76 | x | − | 24 19 | = | x | ÷ | 7 | ÷ | 6 |
| 方程右边 = | x | × | 1 42 |
100 76 | x | − | 24 19 | = | 1 42 | x |
100 76 | x | − | 1 42 | x | = | 24 19 |
1031 798 | x | = | 24 19 |
| x | = | 24 19 | ÷ | 1031 798 |
| = | 24 19 | × | 798 1031 |
| = | 24 | × | 42 1031 |
| x | = | 1008 1031 |
| x | = | 0.977692 |
