| 10000 | ÷ | x | + | 10000 | ÷ | x | + | 28 | = | 150 |
| Multiply both sides of the equation by: | x |
| 10000 | + | 10000 | ÷ | 1 | × | 1 | + | 28 | x | = | 150 | x |
| 28 | x | − | 150 | x | = | - | 10000 | − | 10000 | ÷ | 1 | × | 1 |
| 28 | x | − | 150 | x | = | - | 10000 | − | 10000 |
| - | 122 | x | = | - | 10000 | − | 10000 |
| - | 122 | x | = | - | 20000 |
| 20000 | = | 122 | x |
| 122 | x | = | 20000 |
| x | = | 20000 | ÷ | 122 |
| = | 20000 | × | 1 122 |
| = | 10000 | × | 1 61 |
| x | = | 10000 61 |
| x | = | 163.934426 |
