| 50 | ÷ | 135 | − | 1 10 | = | 79 50000 | ( | 150 | + | X | ) |
| Left side of the equation = | 10 27 | − | 1 10 |
| = | 73 270 |
73 270 | = | 79 50000 | ( | 150 | + | X | ) |
| Right side of the equation = | 79 50000 | × | 150 | + | 79 50000 | X |
| = | 237 1000 | + | 79 50000 | X |
73 270 | = | 237 1000 | + | 79 50000 | X |
| - | 79 50000 | X | = | 237 1000 | − | 73 270 |
| - | 79 50000 | X | = | - | 901 27000 |
901 27000 | = | 79 50000 | X |
79 50000 | X | = | 901 27000 |
| X | = | 901 27000 | ÷ | 79 50000 |
| = | 901 27000 | × | 50000 79 |
| = | 901 27 | × | 50 79 |
| X | = | 45050 2133 |
