| 240 | × | 1000000 | = | 69 5 | × | 300 | x | ( | 590 | − | 1 2 | x | ) |
| Left side of the equation = | 240000000 |
| 240000000 | = | 69 5 | × | 300 | x | ( | 590 | − | 1 2 | x | ) |
| Right side of the equation = | 4140 | x | ( | 590 | − | 1 2 | x | ) |
| 240000000 | = | 4140 | x | ( | 590 | − | 1 2 | x | ) |
| Right side of the equation = | 4140 | x | × | 590 | − | 4140 | x | × | 1 2 | x |
| = | 2442600 | x | − | 2070 | x | x |
| 240000000 | = | 2442600 | x | − | 2070 | x | x |
