| 1087 | ( | 1199 1000 | + | X | ) | = | 1143 | ( | 1061 1000 | + | X | ) |
| Left side of the equation = | 1087 | × | 1199 1000 | + | 1087 | X |
| = | 1303313 1000 | + | 1087 | X |
1303313 1000 | + | 1087 | X | = | 1143 | ( | 1061 1000 | + | X | ) |
| Right side of the equation = | 1143 | × | 1061 1000 | + | 1143 | X |
| = | 1212723 1000 | + | 1143 | X |
1303313 1000 | + | 1087 | X | = | 1212723 1000 | + | 1143 | X |
| 1087 | X | − | 1143 | X | = | 1212723 1000 | − | 1303313 1000 |
| - | 56 | X | = | 1212723 1000 | − | 1303313 1000 |
| - | 56 | X | = | - | 9059 100 |
9059 100 | = | 56 | X |
| 56 | X | = | 9059 100 |
| X | = | 9059 100 | ÷ | 56 |
| = | 9059 100 | × | 1 56 |
| X | = | 9059 5600 |
| X | = | 1.617679 |
