x | ÷ | ( | 1 | − | x | ) | = | 81 100 |
Multiply both sides of the equation by: | ( | 1 | − | x | ) |
x | = | 81 100 | ( | 1 | − | x | ) |
x | = | 81 100 | × | 1 | − | 81 100 | x |
x | = | 81 100 | − | 81 100 | x |
x | + | 81 100 | x | = | 81 100 |
181 100 | x | = | 81 100 |
x | = | 81 100 | ÷ | 181 100 |
= | 81 100 | × | 100 181 |
= | 81 | × | 1 181 |
x | = | 81 181 |
x | = | 0.447514 |
