| 269 | + | x | = | 87 100 | ( | 334 | + | x | ) |
| Right side of the equation = | 87 100 | × | 334 | + | 87 100 | x |
| = | 14529 50 | + | 87 100 | x |
| 269 | + | x | = | 14529 50 | + | 87 100 | x |
| x | − | 87 100 | x | = | 14529 50 | − | 269 |
13 100 | x | = | 14529 50 | − | 269 |
13 100 | x | = | 1079 50 |
| x | = | 1079 50 | ÷ | 13 100 |
| = | 1079 50 | × | 100 13 |
| = | 83 | × | 2 |
| x | = | 166 |
