| X | + | X | × | 1 10 | + | ( | X | + | X | × | 1 10 | ) | = | 798 |
| Left side of the equation = | 11 10 | X | + | ( | X | + | X | × | 1 10 | ) |
11 10 | X | + | ( | X | + | X | × | 1 10 | ) | = | 798 |
| Left side of the equation = | 11 10 | X | + | X | + | X | × | 1 10 |
| = | 11 5 | X |
11 5 | X | = | 798 |
| X | = | 798 | ÷ | 11 5 |
| = | 798 | × | 5 11 |
