Work: Find the solution of equation 20*32-16*16*3.14-（32-2x）/2*（32-2x）/2*3.14 = 540 .
Question type: Equation
Solution:Original question:
| 20 | × | 32 | − | 16 | × | 16 | × | 157 50 | − | ( | 32 | − | 2 | x | ) | ÷ | 2 | × | ( | 32 | − | 2 | x | ) | ÷ | 2 | × | 157 50 | = | 540 |
| Left side of the equation = | 640 | − | 20096 25 | − | ( | 32 | − | 2 | x | ) | × | 157 200 | ( | 32 | − | 2 | x | ) |
| = | - | 4096 25 | − | ( | 32 | − | 2 | x | ) | × | 157 200 | ( | 32 | − | 2 | x | ) |
| - | 4096 25 | − | ( | 32 | − | 2 | x | ) | × | 157 200 | ( | 32 | − | 2 | x | ) | = | 540 |
| Left side of the equation = | - | 4096 25 | − | 32 | × | 157 200 | ( | 32 | − | 2 | x | ) | + | 2 | x | × | 157 200 | ( | 32 | − | 2 | x | ) |
| = | - | 4096 25 | − | 628 25 | ( | 32 | − | 2 | x | ) | + | 157 100 | x | ( | 32 | − | 2 | x | ) |
| = | - | 4096 25 | − | 628 25 | × | 32 | + | 628 25 | × | 2 | x | + | 157 100 | x | ( | 32 | − | 2 | x | ) |
| = | - | 4096 25 | − | 20096 25 | + | 1256 25 | x | + | 157 100 | x | ( | 32 | − | 2 | x | ) |
| = | - | 24192 25 | + | 1256 25 | x | + | 157 100 | x | ( | 32 | − | 2 | x | ) |
