Work: Find the solution of equation （89.43-78.15）/（78.15-78.41） = （81.46-78.15）/（x-78.41) .
Question type: Equation
Solution:Original question:
| ( | 8943 100 | − | 1563 20 | ) | ÷ | ( | 1563 20 | − | 7841 100 | ) | = | ( | 4073 50 | − | 1563 20 | ) | ÷ | ( | x | − | 7841 100 | ) |
| Multiply both sides of the equation by: | ( | 1563 20 | − | 7841 100 | ) | , | ( | x | − | 7841 100 | ) |
| ( | 8943 100 | − | 1563 20 | ) | ( | x | − | 7841 100 | ) | = | ( | 4073 50 | − | 1563 20 | ) | ( | 1563 20 | − | 7841 100 | ) |
8943 100 | ( | x | − | 7841 100 | ) | − | 1563 20 | ( | x | − | 7841 100 | ) | = | ( | 4073 50 | − | 1563 20 | ) | ( | 1563 20 | − | 7841 100 | ) |
