Work: Find the solution of equation (7%-X)/(X-8%) = (4.1002-4)/(4-3.9927) .
Question type: Equation
Solution:Original question:
| ( | 7 100 | − | X | ) | ÷ | ( | X | − | 8 100 | ) | = | ( | 20501 5000 | − | 4 | ) | ÷ | ( | 4 | − | 39927 10000 | ) |
| Multiply both sides of the equation by: | ( | X | − | 8 100 | ) | , | ( | 4 | − | 39927 10000 | ) |
| ( | 7 100 | − | X | ) | ( | 4 | − | 39927 10000 | ) | = | ( | 20501 5000 | − | 4 | ) | ( | X | − | 8 100 | ) |
