| ( | 32 100 | x | − | 24 | ) | ÷ | ( | x | − | 40 | ) | = | 25 100 |
| Multiply both sides of the equation by: | ( | x | − | 40 | ) |
| ( | 32 100 | x | − | 24 | ) | = | 25 100 | ( | x | − | 40 | ) |
32 100 | x | − | 24 | = | 25 100 | ( | x | − | 40 | ) |
32 100 | x | − | 24 | = | 25 100 | x | − | 25 100 | × | 40 |
32 100 | x | − | 24 | = | 25 100 | x | − | 10 |
32 100 | x | − | 25 100 | x | = | - | 10 | + | 24 |
7 100 | x | = | - | 10 | + | 24 |
7 100 | x | = | 14 |
| x | = | 14 | ÷ | 7 100 |
| = | 14 | × | 100 7 |
| = | 2 | × | 100 |
| x | = | 200 |
