113 100 | x | ÷ | 13 100 | + | 103 100 | ( | 99499 | − | x | ) | ÷ | 3 100 | = | 1200000 |
| Left side of the equation = | 113 13 | x | + | 103 3 | ( | 99499 | − | x | ) |
113 13 | x | + | 103 3 | ( | 99499 | − | x | ) | = | 1200000 |
| Left side of the equation = | 113 13 | x | + | 103 3 | × | 99499 | − | 103 3 | x |
| = | 113 13 | x | + | 10248397 3 | − | 103 3 | x |
| = | - | 1000 39 | x | + | 10248397 3 |
| - | 1000 39 | x | + | 10248397 3 | = | 1200000 |
| - | 1000 39 | x | = | 1200000 | − | 10248397 3 |
| - | 1000 39 | x | = | - | 6648397 3 |
6648397 3 | = | 1000 39 | x |
1000 39 | x | = | 6648397 3 |
| x | = | 6648397 3 | ÷ | 1000 39 |
| = | 6648397 3 | × | 39 1000 |
| = | 6648397 | × | 13 1000 |
| x | = | 86429161 1000 |
