| X | − | 1 10 | X | − | 1 20 | X | − | 50 | = | 88 | + | 1 10 | × | 88 |
| Left side of the equation = | 17 20 | X | − | 50 |
17 20 | X | − | 50 | = | 88 | + | 1 10 | × | 88 |
| Right side of the equation = | 88 | + | 44 5 |
| = | 484 5 |
17 20 | X | − | 50 | = | 484 5 |
17 20 | X | = | 484 5 | + | 50 |
17 20 | X | = | 734 5 |
| X | = | 734 5 | ÷ | 17 20 |
| = | 734 5 | × | 20 17 |
| = | 734 | × | 4 17 |
| X | = | 2936 17 |
| X | = | 172.705882 |
