| 134 | ( | 1 | + | x | ) | × | 10 | = | 1558 |
| Left side of the equation = | 1340 | ( | 1 | + | x | ) |
| 1340 | ( | 1 | + | x | ) | = | 1558 |
| Left side of the equation = | 1340 | × | 1 | + | 1340 | x |
| = | 1340 | + | 1340 | x |
| 1340 | + | 1340 | x | = | 1558 |
| 1340 | x | = | 1558 | − | 1340 |
| 1340 | x | = | 218 |
| x | = | 218 | ÷ | 1340 |
| = | 218 | × | 1 1340 |
| = | 109 | × | 1 670 |
| x | = | 109 670 |
| x | = | 0.162687 |
