Work: Find the solution of equation （x-61.3）（79-x） = 155.26 .
Question type: Equation
Solution:Original question:
| ( | x | − | 613 10 | ) | ( | 79 | − | x | ) | = | 7763 50 |
| Left side of the equation = | x | ( | 79 | − | x | ) | − | 613 10 | ( | 79 | − | x | ) |
| = | x | × | 79 | − | x | x | − | 613 10 | ( | 79 | − | x | ) |
| = | 79 | x | − | x | x | − | 613 10 | × | 79 | + | 613 10 | x |
| = | 79 | x | − | x | x | − | 48427 10 | + | 613 10 | x |
| = | 1403 10 | x | − | x | x | − | 48427 10 |
1403 10 | x | − | x | x | − | 48427 10 | = | 7763 50 |
