| ( | 33 10 | − | X | ) | ÷ | 63 | = | 551 10 | X | ÷ | 255 |
| Left side of the equation = | 33 10 | × | 1 63 | − | X | × | 1 63 |
| = | 11 210 | − | X | × | 1 63 |
11 210 | − | 1 63 | X | = | 551 10 | X | ÷ | 255 |
| Right side of the equation = | 551 2550 | X |
11 210 | − | 1 63 | X | = | 551 2550 | X |
| - | 1 63 | X | − | 551 2550 | X | = | - | 11 210 |
| - | 12421 53550 | X | = | - | 11 210 |
11 210 | = | 12421 53550 | X |
12421 53550 | X | = | 11 210 |
| X | = | 11 210 | ÷ | 12421 53550 |
| = | 11 210 | × | 53550 12421 |
