| ( | 111 5 | − | x | ) | ÷ | x | = | - | 71 250 |
| Multiply both sides of the equation by: | x |
| ( | 111 5 | − | x | ) | = | - | 71 250 | x |
111 5 | − | x | = | - | 71 250 | x |
| - | x | + | 71 250 | x | = | - | 111 5 |
| - | 179 250 | x | = | - | 111 5 |
111 5 | = | 179 250 | x |
179 250 | x | = | 111 5 |
| x | = | 111 5 | ÷ | 179 250 |
| = | 111 5 | × | 250 179 |
| = | 111 | × | 50 179 |
| x | = | 5550 179 |
| x | = | 31.005587 |
