| Right side of the equation = | 4 5 | ( | 1 | + | X | ) | ÷ | 10 | + | X |
| = | 2 25 | ( | 1 | + | X | ) | + | X |
| = | 2 25 | × | 1 | + | 2 25 | X | + | X |
| = | 2 25 | + | 2 25 | X | + | X |
| = | 2 25 | + | 27 25 | X |
27 250 | = | 2 25 | + | 27 25 | X |
| - | 27 25 | X | = | 2 25 | − | 27 250 |
| - | 27 25 | X | = | - | 7 250 |
7 250 | = | 27 25 | X |
27 25 | X | = | 7 250 |
| X | = | 7 250 | ÷ | 27 25 |
| = | 7 250 | × | 25 27 |
| = | 7 10 | × | 1 27 |
| X | = | 7 270 |
