[ 1/1 Equation]
Work: Find the solution of equation （20+x）（20.064－x） = （20－x）（20.09+x） .
Question type: Equation
Solution:Original question:
| ( | 20 | + | x | ) | ( | 2508 125 | − | x | ) | = | ( | 20 | − | x | ) | ( | 2009 100 | + | x | ) |
| Left side of the equation = | 20 | ( | 2508 125 | − | x | ) | + | x | ( | 2508 125 | − | x | ) |
| = | 20 | × | 2508 125 | − | 20 | x | + | x | ( | 2508 125 | − | x | ) |
| = | 10032 25 | − | 20 | x | + | x | ( | 2508 125 | − | x | ) |
| = | 10032 25 | − | 20 | x | + | x | × | 2508 125 | − | x | x |
| = | 10032 25 | + | 8 125 | x | − | x | x |
10032 25 | + | 8 125 | x | − | x | x | = | ( | 20 | − | x | ) | ( | 2009 100 | + | x | ) |
| Right side of the equation = | 20 | ( | 2009 100 | + | x | ) | − | x | ( | 2009 100 | + | x | ) |
| = | 20 | × | 2009 100 | + | 20 | x | − | x | ( | 2009 100 | + | x | ) |
| = | 2009 5 | + | 20 | x | − | x | ( | 2009 100 | + | x | ) |
| = | 2009 5 | + | 20 | x | − | x | × | 2009 100 | − | x | x |
| = | 2009 5 | − | 9 100 | x | − | x | x |
10032 25 | + | 8 125 | x | − | x | x | = | 2009 5 | − | 9 100 | x | − | x | x |
