| ( | ( | 164 | − | x | ) | ÷ | x | ) | = | 74 2500 |
| ( | 164 | − | x | ) | ÷ | x | = | 74 2500 |
| Multiply both sides of the equation by: | x |
| ( | 164 | − | x | ) | = | 74 2500 | x |
| 164 | − | x | = | 74 2500 | x |
| - | x | − | 74 2500 | x | = | - | 164 |
| - | 1287 1250 | x | = | - | 164 |
| 164 | = | 1287 1250 | x |
1287 1250 | x | = | 164 |
| x | = | 164 | ÷ | 1287 1250 |
| = | 164 | × | 1250 1287 |
| x | = | 205000 1287 |
| x | = | 159.285159 |
