| ( | 10000 | − | 26 | x | × | 300 | ) | ÷ | ( | 15 | x | × | 300 | ) | = | 2 5 |
| Multiply both sides of the equation by: | ( | 15 | x | × | 300 | ) |
| ( | 10000 | − | 26 | x | × | 300 | ) | = | 2 5 | ( | 15 | x | × | 300 | ) |
| 10000 | − | 26 | x | × | 300 | = | 2 5 | ( | 15 | x | × | 300 | ) |
| 10000 | − | 26 | x | × | 300 | = | 2 5 | × | 15 | x | × | 300 |
| 10000 | − | 7800 | x | = | 1800 | x |
| - | 7800 | x | − | 1800 | x | = | - | 10000 |
| - | 9600 | x | = | - | 10000 |
| 10000 | = | 9600 | x |
| 9600 | x | = | 10000 |
| x | = | 10000 | ÷ | 9600 |
| = | 10000 | × | 1 9600 |
| = | 25 | × | 1 24 |
| x | = | 25 24 |
| x | = | 1.041667 |
