| 200 | ÷ | x | + | ( | 540 | x | − | 200 | ) | ÷ | 5 4 | × | x | = | 540 | − | 36 |
| Multiply both sides of the equation by: | x |
| 200 | + | ( | 540 | x | − | 200 | ) | ÷ | 5 4 | × | x | x | = | 540 | x | − | 36 | x |
| 200 | + | 540 | x | ÷ | 5 4 | × | x | x | − | 200 | ÷ | 5 4 | × | x | x | = | 540 | x | − | 36 | x |
| 200 | + | 432 | x | x | x | − | 160 | x | x | = | 540 | x | − | 36 | x |
| 200 | + | 432 | x | x | x | − | 160 | x | x | = | 504 | x |
