| 1 | ÷ | 500 | + | X | ÷ | 1650 | = | ( | 1 | + | X | ) | ÷ | 1000 |
| Left side of the equation = | 1 500 | + | X | × | 1 1650 |
1 500 | + | 1 1650 | X | = | ( | 1 | + | X | ) | ÷ | 1000 |
| Right side of the equation = | 1 | × | 1 1000 | + | X | × | 1 1000 |
| = | 1 1000 | + | X | × | 1 1000 |
1 500 | + | 1 1650 | X | = | 1 1000 | + | 1 1000 | X |
1 1650 | X | − | 1 1000 | X | = | 1 1000 | − | 1 500 |
| - | 13 33000 | X | = | 1 1000 | − | 1 500 |
| - | 13 33000 | X | = | - | 1 1000 |
1 1000 | = | 13 33000 | X |
13 33000 | X | = | 1 1000 |
| X | = | 1 1000 | ÷ | 13 33000 |
| = | 1 1000 | × | 33000 13 |
| = | 1 | × | 33 13 |
| X | = | 33 13 |
