| 37 | x | = | 4 5 | × | 3 | ( | 240000 | + | x | ) |
| Right side of the equation = | 12 5 | ( | 240000 | + | x | ) |
| 37 | x | = | 12 5 | ( | 240000 | + | x | ) |
| Right side of the equation = | 12 5 | × | 240000 | + | 12 5 | x |
| = | 576000 | + | 12 5 | x |
| 37 | x | = | 576000 | + | 12 5 | x |
| 37 | x | − | 12 5 | x | = | 576000 |
173 5 | x | = | 576000 |
| x | = | 576000 | ÷ | 173 5 |
| = | 576000 | × | 5 173 |
| x | = | 2880000 173 |
| x | = | 16647.398844 |
