1 16 | = | ( | 1 | + | x | ) | ÷ | x | × | 2 5 | × | 1 40 |
| Multiply both sides of the equation by: | x |
1 16 | x | = | ( | 1 | + | x | ) | × | 2 5 | × | 1 40 |
1 16 | x | = | 1 | × | 2 5 | × | 1 40 | + | x | × | 2 5 | × | 1 40 |
1 16 | x | = | 1 100 | + | x | × | 1 100 |
1 16 | x | − | 1 100 | x | = | 1 100 |
21 400 | x | = | 1 100 |
| x | = | 1 100 | ÷ | 21 400 |
| = | 1 100 | × | 400 21 |
| = | 1 | × | 4 21 |
| x | = | 4 21 |
| x | = | 0.190476 |
