| ( | 500 | + | 5 | x | + | 63 | ) | ÷ | ( | x | + | 141 | ) | = | 237 50 |
| Multiply both sides of the equation by: | ( | x | + | 141 | ) |
| ( | 500 | + | 5 | x | + | 63 | ) | = | 237 50 | ( | x | + | 141 | ) |
| 500 | + | 5 | x | + | 63 | = | 237 50 | ( | x | + | 141 | ) |
| 500 | + | 5 | x | + | 63 | = | 237 50 | x | + | 237 50 | × | 141 |
| 500 | + | 5 | x | + | 63 | = | 237 50 | x | + | 33417 50 |
| 563 | + | 5 | x | = | 237 50 | x | + | 33417 50 |
| 5 | x | − | 237 50 | x | = | 33417 50 | − | 563 |
13 50 | x | = | 33417 50 | − | 563 |
13 50 | x | = | 5267 50 |
| x | = | 5267 50 | ÷ | 13 50 |
| = | 5267 50 | × | 50 13 |
| = | 5267 | × | 1 13 |
| x | = | 5267 13 |
| x | = | 405.153846 |
