| x | ÷ | 525 | − | x | = | x | ÷ | 350 | − | x |
| Left side of the equation = | - | 524 525 | x |
| - | 524 525 | x | = | x | ÷ | 350 | − | x |
| Right side of the equation = | - | 349 350 | x |
| - | 524 525 | x | = | - | 349 350 | x |
| - | 524 525 | x | + | 349 350 | x | = | 0 |
| - | 1 1050 | x | = | 0 |
| - | 0 | = | 1 1050 | x |
1 1050 | x | = | - | 0 |
| x | = | - | 0 | ÷ | 1 1050 |
| = | - | 0 | × | 1050 |
| x | = | 0 |
