| 4 | ( | - | x | + | 8 5 | × | 597 | ) | = | 1 | ( | - | x | + | 3 | × | 523 | ) |
| Left side of the equation = | - | 4 | x | + | 4 | × | 8 5 | × | 597 |
| = | - | 4 | x | + | 19104 5 |
| - | 4 | x | + | 19104 5 | = | 1 | ( | - | x | + | 3 | × | 523 | ) |
| Right side of the equation = | - | 1 | x | + | 1 | × | 3 | × | 523 |
| = | - | 1 | x | + | 1569 |
| - | 4 | x | + | 19104 5 | = | - | 1 | x | + | 1569 |
| - | 4 | x | + | 1 | x | = | 1569 | − | 19104 5 |
| - | 3 | x | = | 1569 | − | 19104 5 |
| - | 3 | x | = | - | 11259 5 |
11259 5 | = | 3 | x |
| 3 | x | = | 11259 5 |
| x | = | 11259 5 | ÷ | 3 |
| = | 11259 5 | × | 1 3 |
