| ( | 5 | ( | 435 | X | ) | + | 248 | ) | ÷ | ( | 537 | + | X | ) | = | 23 5 |
| Multiply both sides of the equation by: | ( | 537 | + | X | ) |
| ( | 5 | ( | 435 | X | ) | + | 248 | ) | = | 23 5 | ( | 537 | + | X | ) |
| 5 | ( | 435 | X | ) | + | 248 | = | 23 5 | ( | 537 | + | X | ) |
| 5 | ( | 435 | X | ) | + | 248 | = | 23 5 | × | 537 | + | 23 5 | X |
| 5 | ( | 435 | X | ) | + | 248 | = | 12351 5 | + | 23 5 | X |
| 5 | × | 435 | X | + | 248 | = | 12351 5 | + | 23 5 | X |
| 2175 | X | + | 248 | = | 12351 5 | + | 23 5 | X |
| 2175 | X | − | 23 5 | X | = | 12351 5 | − | 248 |
10852 5 | X | = | 12351 5 | − | 248 |
10852 5 | X | = | 11111 5 |
| X | = | 11111 5 | ÷ | 10852 5 |
| = | 11111 5 | × | 5 10852 |
| = | 11111 | × | 1 10852 |
| X | = | 11111 10852 |
| X | = | 1.023867 |
