Question type: Equation
Solution:Original question:
| X | − | X | ÷ | 109 100 | × | 9 100 | − | X | ÷ | 109 100 | × | 9 100 | × | 7 100 | − | X | ÷ | 109 100 | × | 9 100 | × | 3 100 | = | 157081232 25 |
| Left side of the equation = | X | − | X | × | 9 109 | − | X | × | 63 10900 | − | X | × | 27 10900 | − | X | × | 9 5450 |
| = | 2473 2725 | X |
2473 2725 | X | = | 157081232 25 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 157081232 25 | ÷ | 2473 2725 |
| = | 157081232 25 | × | 2725 2473 |
| = | 157081232 | × | 109 2473 |
We obtained :
| X | = | 17121854288 2473 |
