| x | ÷ | ( | 350 | + | x | ) | = | 9 1000 |
| Multiply both sides of the equation by: | ( | 350 | + | x | ) |
| x | = | 9 1000 | ( | 350 | + | x | ) |
| x | = | 9 1000 | × | 350 | + | 9 1000 | x |
| x | = | 63 20 | + | 9 1000 | x |
| x | − | 9 1000 | x | = | 63 20 |
991 1000 | x | = | 63 20 |
| x | = | 63 20 | ÷ | 991 1000 |
| = | 63 20 | × | 1000 991 |
| = | 63 | × | 50 991 |
| x | = | 3150 991 |
| x | = | 3.178607 |
