6 5 | x | × | 4000 | ÷ | x | = | 4080 | ÷ | x | − | 3 |
| Multiply both sides of the equation by: | x |
6 5 | x | × | 4000 | = | 4080 | ÷ | 1 | × | 1 | − | 3 | x |
6 5 | x | × | 4000 | + | 3 | x | = | 4080 | ÷ | 1 | × | 1 |
| 4800 | x | + | 3 | x | = | 4080 | ÷ | 1 | × | 1 |
| 4800 | x | + | 3 | x | = | 4080 |
| 4803 | x | = | 4080 |
| x | = | 4080 | ÷ | 4803 |
| = | 4080 | × | 1 4803 |
| = | 1360 | × | 1 1601 |
| x | = | 1360 1601 |
| x | = | 0.849469 |
