1 10 | x | ÷ | ( | 8000 | + | x | ) | = | 1 2 | ÷ | 100 |
| Multiply both sides of the equation by: | ( | 8000 | + | x | ) |
1 10 | x | = | 1 2 | ÷ | 100 | × | ( | 8000 | + | x | ) |
1 10 | x | = | 1 2 | ÷ | 100 | × | 8000 | + | 1 2 | ÷ | 100 | × | x |
1 10 | x | = | 40 | + | 1 200 | x |
1 10 | x | − | 1 200 | x | = | 40 |
19 200 | x | = | 40 |
| x | = | 40 | ÷ | 19 200 |
| = | 40 | × | 200 19 |
| x | = | 8000 19 |
| x | = | 421.052632 |
