1 2 | ( | 1 200 | x | ÷ | ( | 1200 | − | x | ) | × | 28600 | × | 4000 | x | ) | = | 100531 20 | × | 500 | + | 140 | × | 16 | × | 165000 | × | 1 200 |
1 2 | × | 1 200 | x | ÷ | ( | 1200 | − | x | ) | × | 28600 | × | 4000 | x | = | 100531 20 | × | 500 | + | 140 | × | 16 | × | 165000 | × | 1 200 |
| 286000 | x | ÷ | ( | 1200 | − | x | ) | × | x | = | 2513275 | + | 1848000 |
| 286000 | x | ÷ | ( | 1200 | − | x | ) | × | x | = | 4361275 |
| Multiply both sides of the equation by: | ( | 1200 | − | x | ) |
| 286000 | x | x | = | 4361275 | ( | 1200 | − | x | ) |
| 286000 | x | x | = | 4361275 | × | 1200 | − | 4361275 | x |
| 286000 | x | x | = | 5233530000 | − | 4361275 | x |
