| 150 | × | 10 | × | 10 | × | 10 | × | 10 | × | 10 | × | 10 | = | 48 5 | × | 250 | x | ( | 465 | − | x | ÷ | 2 | ) |
| Left side of the equation = | 150000000 |
| 150000000 | = | 48 5 | × | 250 | x | ( | 465 | − | x | ÷ | 2 | ) |
| Right side of the equation = | 2400 | x | ( | 465 | − | x | ÷ | 2 | ) |
| 150000000 | = | 2400 | x | ( | 465 | − | x | ÷ | 2 | ) |
| Right side of the equation = | 2400 | x | × | 465 | − | 2400 | x | x | ÷ | 2 |
| = | 1116000 | x | − | 1200 | x | x |
| 150000000 | = | 1116000 | x | − | 1200 | x | x |
