| ( | 5 | ( | 436 | + | x | ) | + | 734 | ) | ÷ | ( | 693 | + | x | ) | = | 9 2 |
| Multiply both sides of the equation by: | ( | 693 | + | x | ) |
| ( | 5 | ( | 436 | + | x | ) | + | 734 | ) | = | 9 2 | ( | 693 | + | x | ) |
| 5 | ( | 436 | + | x | ) | + | 734 | = | 9 2 | ( | 693 | + | x | ) |
| 5 | ( | 436 | + | x | ) | + | 734 | = | 9 2 | × | 693 | + | 9 2 | x |
| 5 | ( | 436 | + | x | ) | + | 734 | = | 6237 2 | + | 9 2 | x |
| 5 | × | 436 | + | 5 | x | + | 734 | = | 6237 2 | + | 9 2 | x |
| 2180 | + | 5 | x | + | 734 | = | 6237 2 | + | 9 2 | x |
| 2914 | + | 5 | x | = | 6237 2 | + | 9 2 | x |
| 5 | x | − | 9 2 | x | = | 6237 2 | − | 2914 |
1 2 | x | = | 6237 2 | − | 2914 |
1 2 | x | = | 409 2 |
| x | = | 409 2 | ÷ | 1 2 |
| = | 409 2 | × | 2 |
| = | 409 | × | 1 |
| x | = | 409 |
