| 25100 | ÷ | ( | x | + | 112 5 | ) | = | 150 |
| Multiply both sides of the equation by: | ( | x | + | 112 5 | ) |
| 25100 | = | 150 | ( | x | + | 112 5 | ) |
| 25100 | = | 150 | x | + | 150 | × | 112 5 |
| 25100 | = | 150 | x | + | 3360 |
| - | 150 | x | = | 3360 | − | 25100 |
| - | 150 | x | = | - | 21740 |
| 21740 | = | 150 | x |
| 150 | x | = | 21740 |
| x | = | 21740 | ÷ | 150 |
| = | 21740 | × | 1 150 |
| = | 2174 | × | 1 15 |
| x | = | 2174 15 |
| x | = | 144.933333 |
