9 100 | = | ( | 3 5 | ( | 1 | + | 4 100 | ) | ) | ÷ | x | + | 4 100 |
| Multiply both sides of the equation by: | x |
9 100 | x | = | ( | 3 5 | ( | 1 | + | 4 100 | ) | ) | + | 4 100 | x |
9 100 | x | = | 3 5 | ( | 1 | + | 4 100 | ) | + | 4 100 | x |
9 100 | x | = | 3 5 | × | 1 | + | 3 5 | × | 4 100 | + | 4 100 | x |
9 100 | x | = | 3 5 | + | 3 125 | + | 4 100 | x |
9 100 | x | = | 78 125 | + | 4 100 | x |
9 100 | x | − | 4 100 | x | = | 78 125 |
1 20 | x | = | 78 125 |
| x | = | 78 125 | ÷ | 1 20 |
| = | 78 125 | × | 20 |
| = | 78 25 | × | 4 |
| x | = | 312 25 |
| x | = | 12.48 |
