Work: Find the solution of equation 0.998 = (1-(0.15-0.0077)/(x-0.0077))*(1-0.0077)/0.85 .
Question type: Equation
Solution:Original question:
499 500 | = | ( | 1 | − | ( | 3 20 | − | 77 10000 | ) | ÷ | ( | x | − | 77 10000 | ) | ) | ( | 1 | − | 77 10000 | ) | ÷ | 17 20 |
499 500 | = | 1 | ( | 1 | − | 77 10000 | ) | ÷ | 17 20 | − | ( | 3 20 | − | 77 10000 | ) | ÷ | ( | x | − | 77 10000 | ) | × | ( | 1 | − | 77 10000 | ) | ÷ | 17 20 |
499 500 | = | 20 17 | ( | 1 | − | 77 10000 | ) | − | ( | 3 20 | − | 77 10000 | ) | ÷ | ( | x | − | 77 10000 | ) | × | ( | 1 | − | 77 10000 | ) | × | 20 17 |
| Multiply both sides of the equation by: | ( | x | − | 77 10000 | ) |
499 500 | ( | x | − | 77 10000 | ) | = | 20 17 | ( | 1 | − | 77 10000 | ) | ( | x | − | 77 10000 | ) | − | ( | 3 20 | − | 77 10000 | ) | ( | 1 | − | 77 10000 | ) | × | 20 17 |
