| x | + | 15 100 | x | + | ( | ( | x | + | 15 100 | x | ) | × | 5 100 | ) | = | 4591 20 |
| Left side of the equation = | 23 20 | x | + | ( | ( | x | + | 15 100 | x | ) | × | 5 100 | ) |
23 20 | x | + | ( | ( | x | + | 15 100 | x | ) | × | 5 100 | ) | = | 4591 20 |
| Left side of the equation = | 23 20 | x | + | ( | x | + | 15 100 | x | ) | × | 5 100 |
| = | 23 20 | x | + | x | × | 5 100 | + | 15 100 | x | × | 5 100 |
| = | 23 20 | x | + | x | × | 5 100 | + | 3 400 | x |
| = | 483 400 | x |
483 400 | x | = | 4591 20 |
| x | = | 4591 20 | ÷ | 483 400 |
| = | 4591 20 | × | 400 483 |
