| ( | 2403 50 | − | x | ) | ÷ | x | = | 1221 1000 |
| Multiply both sides of the equation by: | x |
| ( | 2403 50 | − | x | ) | = | 1221 1000 | x |
2403 50 | − | x | = | 1221 1000 | x |
| - | x | − | 1221 1000 | x | = | - | 2403 50 |
| - | 2221 1000 | x | = | - | 2403 50 |
2403 50 | = | 2221 1000 | x |
2221 1000 | x | = | 2403 50 |
| x | = | 2403 50 | ÷ | 2221 1000 |
| = | 2403 50 | × | 1000 2221 |
| = | 2403 | × | 20 2221 |
