| 109650 | + | ( | 1 100 | X | + | 15750 | ) | + | 27 500 | X | = | X |
| Left side of the equation = | 109650 | + | 1 100 | X | + | 15750 | + | 27 500 | X |
| = | 125400 | + | 8 125 | X |
| 125400 | + | 8 125 | X | = | X |
8 125 | X | − | X | = | - | 125400 |
| - | 117 125 | X | = | - | 125400 |
| 125400 | = | 117 125 | X |
117 125 | X | = | 125400 |
| X | = | 125400 | ÷ | 117 125 |
| = | 125400 | × | 125 117 |
| = | 41800 | × | 125 39 |
