Question type: Equation
Solution:Original question:
9 10 | × | 657 25 | × | 270 | × | 84 | + | 391 20 | × | 270 | ( | x | − | 84 | ) | = | 462 | × | 443 | + | 9 10 | × | 509 | × | 459 | − | 9 10 | × | 402 | × | 440 | − | 660 | ( | 5 4 | x | − | 84 | − | 25 | ) | ÷ | ( | 5 4 | x | − | 84 | ) |
| Multiply both sides of the equation by: | ( | 5 4 | x | − | 84 | ) |
