| Left side of the equation = | 5699 1000 | × | 200 | − | 1121 200 | × | 200 | + | ( | 1141 200 | − | 1121 200 | ) | × | 100 | − | 2 5 | − | ( | 5759 1000 | − | x | ) | × | 200 |
| = | 5699 5 | − | 1121 | + | ( | 1141 200 | − | 1121 200 | ) | × | 100 | − | 2 5 | − | ( | 5759 1000 | − | x | ) | × | 200 |
| = | 92 5 | + | ( | 1141 200 | − | 1121 200 | ) | × | 100 | − | ( | 5759 1000 | − | x | ) | × | 200 |
| = | 92 5 | + | 1141 200 | × | 100 | − | 1121 200 | × | 100 | − | ( | 5759 1000 | − | x | ) | × | 200 |

| = | 142 5 | − | ( | 5759 1000 | − | x | ) | × | 200 |
| = | 142 5 | − | 5759 1000 | × | 200 | + | x | × | 200 |
| = | 142 5 | − | 5759 5 | + | x | × | 200 |
| = | - | 5617 5 | + | 200 | x |
| - | 5617 5 | + | 200 | x | = | 281 10 |
Transposition :
| 200 | x | = | 281 10 | + | 5617 5 |
Combine the items on the right of the equation:
| 200 | x | = | 2303 2 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2303 2 | ÷ | 200 |
| = | 2303 2 | × | 1 200 |
We obtained :
| x | = | 2303 400 |
Convert the result to decimal form :
| x | = | 5.7575 |
