| 18750 | + | x | = | 1 10 | ( | 625000 | + | x | ) |
| Right side of the equation = | 1 10 | × | 625000 | + | 1 10 | x |
| = | 62500 | + | 1 10 | x |
| 18750 | + | x | = | 62500 | + | 1 10 | x |
| x | − | 1 10 | x | = | 62500 | − | 18750 |
9 10 | x | = | 62500 | − | 18750 |
9 10 | x | = | 43750 |
| x | = | 43750 | ÷ | 9 10 |
| = | 43750 | × | 10 9 |
| x | = | 437500 9 |
| x | = | 48611.111111 |
