| 50000 | = | ( | 150 | + | x | ) | × | 3 | ( | x | ÷ | 9 | ) |
| Right side of the equation = | 150 | × | 3 | ( | x | ÷ | 9 | ) | + | x | × | 3 | ( | x | ÷ | 9 | ) |
| = | 450 | ( | x | ÷ | 9 | ) | + | x | × | 3 | ( | x | ÷ | 9 | ) |
| = | 450 | x | ÷ | 9 | + | x | × | 3 | ( | x | ÷ | 9 | ) |
| = | 50 | x | + | x | × | 3 | ( | x | ÷ | 9 | ) |
| = | 50 | x | + | x | × | 3 | x | ÷ | 9 |
| = | 50 | x | + | x | × | 1 3 | x |
| 50000 | = | 50 | x | + | x | × | 1 3 | x |
