| 48 | − | x | × | 50 | − | x | = | x | − | 18 | x |
| Left side of the equation = | 48 | − | 51 | x |
| 48 | − | 51 | x | = | x | − | 18 | x |
| Right side of the equation = | - | 17 | x |
| 48 | − | 51 | x | = | - | 17 | x |
| - | 51 | x | + | 17 | x | = | - | 48 |
| - | 34 | x | = | - | 48 |
| 48 | = | 34 | x |
| 34 | x | = | 48 |
| x | = | 48 | ÷ | 34 |
| = | 48 | × | 1 34 |
| = | 24 | × | 1 17 |
| x | = | 24 17 |
| x | = | 1.411765 |
