5 100 | = | ( | X | − | 1070 | ) | ÷ | 1070 |
| Right side of the equation = | X | × | 1 1070 | − | 1070 | × | 1 1070 |
| = | X | × | 1 1070 | − | 1 |
5 100 | = | 1 1070 | X | − | 1 |
| - | 1 1070 | X | = | - | 1 | − | 5 100 |
| - | 1 1070 | X | = | - | 21 20 |
21 20 | = | 1 1070 | X |
1 1070 | X | = | 21 20 |
| X | = | 21 20 | ÷ | 1 1070 |
| = | 21 20 | × | 1070 |
| = | 21 2 | × | 107 |
| X | = | 2247 2 |
| X | = | 1123.5 |
