| ( | 59 | ( | 1 | + | 20 100 | ) | ) | + | ( | 5 100 | x | ) | = | x |
| Left side of the equation = | 59 | ( | 1 | + | 20 100 | ) | + | ( | 5 100 | x | ) |
| = | 59 | × | 1 | + | 59 | × | 20 100 | + | ( | 5 100 | x | ) |
| = | 59 | + | 59 5 | + | ( | 5 100 | x | ) |
| = | 354 5 | + | ( | 5 100 | x | ) |
| = | 354 5 | + | 5 100 | x |
354 5 | + | 5 100 | x | = | x |
5 100 | x | − | x | = | - | 354 5 |
| - | 19 20 | x | = | - | 354 5 |
354 5 | = | 19 20 | x |
19 20 | x | = | 354 5 |
| x | = | 354 5 | ÷ | 19 20 |
| = | 354 5 | × | 20 19 |
| = | 354 | × | 4 19 |
| x | = | 1416 19 |
| x | = | 74.526316 |
