| = | 1851 1250 | x | + | 155149 500 | − | 296 5 | − | 148 |
| = | 1851 1250 | x | + | 51549 500 |
1851 1250 | x | + | 51549 500 | = | 2 |
Transposition :
1851 1250 | x | = | 2 | − | 51549 500 |
Combine the items on the right of the equation:
1851 1250 | x | = | - | 50549 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 50549 500 | ÷ | 1851 1250 |
| = | - | 50549 500 | × | 1250 1851 |
| = | - | 50549 2 | × | 5 1851 |
We obtained :
| x | = | - | 252745 3702 |
Convert the result to decimal form :
| x | = | - 68.272555 |
