| 16 | + | 13 100 | X | = | 8 | + | 19 100 | ( | X | − | 30 | ) |
| Right side of the equation = | 8 | + | 19 100 | X | − | 19 100 | × | 30 |
| = | 8 | + | 19 100 | X | − | 57 10 |
| = | 23 10 | + | 19 100 | X |
| 16 | + | 13 100 | X | = | 23 10 | + | 19 100 | X |
13 100 | X | − | 19 100 | X | = | 23 10 | − | 16 |
| - | 3 50 | X | = | 23 10 | − | 16 |
| - | 3 50 | X | = | - | 137 10 |
137 10 | = | 3 50 | X |
3 50 | X | = | 137 10 |
| X | = | 137 10 | ÷ | 3 50 |
| = | 137 10 | × | 50 3 |
| = | 137 | × | 5 3 |
| X | = | 685 3 |
| X | = | 228.333333 |
