| x | × | 5 | ( | 120 | ÷ | 26000 | + | 180 | ÷ | 40000 | + | 60 | ÷ | 60000 | ) | = | 1 |
| Left side of the equation = | x | × | 5 | × | 120 | ÷ | 26000 | + | x | × | 5 | × | 180 | ÷ | 40000 | + | x | × | 5 | × | 60 | ÷ | 60000 |
| = | x | × | 3 130 | + | x | × | 9 400 | + | x | × | 1 200 |
| = | 263 5200 | x |
263 5200 | x | = | 1 |
| x | = | 1 | ÷ | 263 5200 |
| = | 1 | × | 5200 263 |
| x | = | 5200 263 |
| x | = | 19.771863 |
