Question type: Equation
Solution:Original question:
9189 2000 | = | ( | ( | 1401 50 | × | 639 1000 | ( | x | + | 1 10 | ) | ) | ÷ | ( | 1 | + | 639 1000 | ( | x | + | 1 10 | ) | ) | × | ( | ( | 1 | − | 333 50 | − | 57 50 | ) | ÷ | 100 | ) | ( | 1 | ÷ | ( | 1 | + | 31 100 | × | 57 50 | ) | + | ( | ( | 19 25 | ( | x | + | 1 10 | ) | ) | ÷ | ( | 13 10 | × | 4053 40000 | ) | ) | ) | ) |
9189 2000 | = | ( | 1401 50 | × | 639 1000 | ( | x | + | 1 10 | ) | ) | ÷ | ( | 1 | + | 639 1000 | ( | x | + | 1 10 | ) | ) | × | ( | ( | 1 | − | 333 50 | − | 57 50 | ) | ÷ | 100 | ) | ( | 1 | ÷ | ( | 1 | + | 31 100 | × | 57 50 | ) | + | ( | ( | 19 25 | ( | x | + | 1 10 | ) | ) | ÷ | ( | 13 10 | × | 4053 40000 | ) | ) | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 639 1000 | ( | x | + | 1 10 | ) | ) |
