| 1500 | ( | 1 | − | x | ) | + | 1000 | x | = | 876 |
| Left side of the equation = | 1500 | × | 1 | − | 1500 | x | + | 1000 | x |
| = | 1500 | − | 1500 | x | + | 1000 | x |
| = | 1500 | − | 500 | x |
| 1500 | − | 500 | x | = | 876 |
| - | 500 | x | = | 876 | − | 1500 |
| - | 500 | x | = | - | 624 |
| 624 | = | 500 | x |
| 500 | x | = | 624 |
| x | = | 624 | ÷ | 500 |
| = | 624 | × | 1 500 |
| = | 156 | × | 1 125 |
| x | = | 156 125 |
| x | = | 1.248 |
