| ( | 18 25 | + | x | ) | ÷ | ( | 3 5000 | + | 10 | x | ) | = | 11 |
| Multiply both sides of the equation by: | ( | 3 5000 | + | 10 | x | ) |
| ( | 18 25 | + | x | ) | = | 11 | ( | 3 5000 | + | 10 | x | ) |
18 25 | + | x | = | 11 | ( | 3 5000 | + | 10 | x | ) |
18 25 | + | x | = | 11 | × | 3 5000 | + | 11 | × | 10 | x |
18 25 | + | x | = | 33 5000 | + | 110 | x |
| x | − | 110 | x | = | 33 5000 | − | 18 25 |
| - | 109 | x | = | 33 5000 | − | 18 25 |
| - | 109 | x | = | - | 3567 5000 |
3567 5000 | = | 109 | x |
| 109 | x | = | 3567 5000 |
| x | = | 3567 5000 | ÷ | 109 |
| = | 3567 5000 | × | 1 109 |
| x | = | 3567 545000 |
| x | = | 0.006545 |
