| 10 | = | ( | 10 | + | x | ) | × | 53 200 |
| Right side of the equation = | 10 | × | 53 200 | + | x | × | 53 200 |
| = | 53 20 | + | x | × | 53 200 |
| 10 | = | 53 20 | + | 53 200 | x |
| - | 53 200 | x | = | 53 20 | − | 10 |
| - | 53 200 | x | = | - | 147 20 |
147 20 | = | 53 200 | x |
53 200 | x | = | 147 20 |
| x | = | 147 20 | ÷ | 53 200 |
| = | 147 20 | × | 200 53 |
| = | 147 | × | 10 53 |
| x | = | 1470 53 |
| x | = | 27.735849 |
