| ( | 15 | − | x | ) | ÷ | 4700 | + | ( | 27 2 | − | x | ) | ÷ | 100000 | = | x | ÷ | 4700 |
| Left side of the equation = | 15 | × | 1 4700 | − | x | × | 1 4700 | + | ( | 27 2 | − | x | ) | × | 1 100000 |
| = | 3 940 | − | x | × | 1 4700 | + | ( | 27 2 | − | x | ) | × | 1 100000 |
| = | 3 940 | − | 1 4700 | x | + | 27 2 | × | 1 100000 | − | x | × | 1 100000 |
| = | 3 940 | − | 1 4700 | x | + | 27 200000 | − | x | × | 1 100000 |
| = | 31269 9400000 | − | 1047 4700000 | x |
31269 9400000 | − | 1047 4700000 | x | = | x | ÷ | 4700 |
| - | 1047 4700000 | x | − | 1 4700 | x | = | - | 31269 9400000 |
