| 14 | × | 8 500 | + | 7 1000 | X | + | 7 2000 | × | 110 | = | 7 2000 | X | + | 40 100 | × | 3 200 | X |
| Left side of the equation = | 28 125 | + | 7 1000 | X | + | 77 200 |
| = | 609 1000 | + | 7 1000 | X |
609 1000 | + | 7 1000 | X | = | 7 2000 | X | + | 40 100 | × | 3 200 | X |
| Right side of the equation = | 7 2000 | X | + | 3 500 | X |
| = | 19 2000 | X |
609 1000 | + | 7 1000 | X | = | 19 2000 | X |
7 1000 | X | − | 19 2000 | X | = | - | 609 1000 |
| - | 1 400 | X | = | - | 609 1000 |
609 1000 | = | 1 400 | X |
1 400 | X | = | 609 1000 |
| X | = | 609 1000 | ÷ | 1 400 |
| = | 609 1000 | × | 400 |
| = | 609 5 | × | 2 |
| X | = | 1218 5 |
