Question type: Equation
Solution:Original question:
| 120000 | − | ( | x | + | 3 100 | x | ) | − | ( | 1380531 100 | − | 3 100 | x | ) | × | 3 25 | = | 2613451 100 |
| Left side of the equation = | 120000 | − | x | − | 3 100 | x | − | ( | 1380531 100 | − | 3 100 | x | ) | × | 3 25 |
| = | 120000 | − | 103 100 | x | − | ( | 1380531 100 | − | 3 100 | x | ) | × | 3 25 |
| = | 120000 | − | 103 100 | x | − | 1380531 100 | × | 3 25 | + | 3 100 | x | × | 3 25 |
| = | 120000 | − | 103 100 | x | − | 4141593 2500 | + | 9 2500 | x |
| = | 295858407 2500 | − | 1283 1250 | x |
295858407 2500 | − | 1283 1250 | x | = | 2613451 100 |
Transposition :
| - | 1283 1250 | x | = | 2613451 100 | − | 295858407 2500 |
