| x | ÷ | ( | x | + | 1973 100 | ) | = | 2 5 |
| Multiply both sides of the equation by: | ( | x | + | 1973 100 | ) |
| x | = | 2 5 | ( | x | + | 1973 100 | ) |
| x | = | 2 5 | x | + | 2 5 | × | 1973 100 |
| x | = | 2 5 | x | + | 1973 250 |
| x | − | 2 5 | x | = | 1973 250 |
3 5 | x | = | 1973 250 |
| x | = | 1973 250 | ÷ | 3 5 |
| = | 1973 250 | × | 5 3 |
| = | 1973 50 | × | 1 3 |
| x | = | 1973 150 |
| x | = | 13.153333 |
