| ( | x | − | 1219 100 | ) | ÷ | 1219 100 | = | 39 100 |
| Left side of the equation = | x | × | 100 1219 | − | 1219 100 | × | 100 1219 |
| = | x | × | 100 1219 | − | 1 |
100 1219 | x | − | 1 | = | 39 100 |
100 1219 | x | = | 39 100 | + | 1 |
100 1219 | x | = | 139 100 |
| x | = | 139 100 | ÷ | 100 1219 |
| = | 139 100 | × | 1219 100 |
| x | = | 169441 10000 |
