| ( | 500 | × | 523 1000 | + | x | ) | ÷ | ( | 500 | + | x | ) | = | 3 5 |
| Multiply both sides of the equation by: | ( | 500 | + | x | ) |
| ( | 500 | × | 523 1000 | + | x | ) | = | 3 5 | ( | 500 | + | x | ) |
| 500 | × | 523 1000 | + | x | = | 3 5 | ( | 500 | + | x | ) |
| 500 | × | 523 1000 | + | x | = | 3 5 | × | 500 | + | 3 5 | x |
523 2 | + | x | = | 300 | + | 3 5 | x |
| x | − | 3 5 | x | = | 300 | − | 523 2 |
2 5 | x | = | 300 | − | 523 2 |
2 5 | x | = | 77 2 |
| x | = | 77 2 | ÷ | 2 5 |
| = | 77 2 | × | 5 2 |
| x | = | 385 4 |
| x | = | 96.25 |
