| ( | x | + | ( | x | × | 3 10 | ) | ) | × | 3 50 | + | x | + | ( | x | × | 3 10 | ) | = | 52040 |
| Left side of the equation = | x | × | 3 50 | + | ( | x | × | 3 10 | ) | × | 3 50 | + | x | + | ( | x | × | 3 10 | ) |
| = | 53 50 | x | + | ( | x | × | 3 10 | ) | × | 3 50 | + | ( | x | × | 3 10 | ) |
| = | 53 50 | x | + | x | × | 3 10 | × | 3 50 | + | ( | x | × | 3 10 | ) |
| = | 53 50 | x | + | x | × | 9 500 | + | ( | x | × | 3 10 | ) |
| = | 539 500 | x | + | ( | x | × | 3 10 | ) |
| = | 539 500 | x | + | x | × | 3 10 |
| = | 689 500 | x |
689 500 | x | = | 52040 |
| x | = | 52040 | ÷ | 689 500 |
| = | 52040 | × | 500 689 |
