15 | = | 100 | ( | x | − | 216 | ) | ÷ | ( | x | × | 190 | ÷ | 100 | ) |
Multiply both sides of the equation by: | ( | x | × | 190 | ÷ | 100 | ) |
15 | ( | x | × | 190 | ÷ | 100 | ) | = | 100 | ( | x | − | 216 | ) |
15 | x | × | 190 | ÷ | 100 | = | 100 | ( | x | − | 216 | ) |
15 | x | × | 190 | ÷ | 100 | = | 100 | x | − | 100 | × | 216 |
57 2 | x | = | 100 | x | − | 21600 |
57 2 | x | − | 100 | x | = | - | 21600 |
- | 143 2 | x | = | - | 21600 |
21600 | = | 143 2 | x |
143 2 | x | = | 21600 |
x | = | 21600 | ÷ | 143 2 |
= | 21600 | × | 2 143 |
x | = | 43200 143 |
x | = | 302.097902 |
