| ( | 100000 | + | 1600 | x | ) | ÷ | 3800 | = | x |
| Left side of the equation = | 100000 | × | 1 3800 | + | 1600 | x | × | 1 3800 |
| = | 500 19 | + | 8 19 | x |
500 19 | + | 8 19 | x | = | x |
8 19 | x | − | x | = | - | 500 19 |
| - | 11 19 | x | = | - | 500 19 |
500 19 | = | 11 19 | x |
11 19 | x | = | 500 19 |
| x | = | 500 19 | ÷ | 11 19 |
| = | 500 19 | × | 19 11 |
| = | 500 | × | 1 11 |
| x | = | 500 11 |
| x | = | 45.454545 |
