| x | ÷ | ( | 100 | + | x | ) | = | 107 1250 |
| Multiply both sides of the equation by: | ( | 100 | + | x | ) |
| x | = | 107 1250 | ( | 100 | + | x | ) |
| x | = | 107 1250 | × | 100 | + | 107 1250 | x |
| x | = | 214 25 | + | 107 1250 | x |
| x | − | 107 1250 | x | = | 214 25 |
1143 1250 | x | = | 214 25 |
| x | = | 214 25 | ÷ | 1143 1250 |
| = | 214 25 | × | 1250 1143 |
| = | 214 | × | 50 1143 |
| x | = | 10700 1143 |
| x | = | 9.36133 |
