Work: Find the solution of equation （477.1-420.8x）(0.966-0.05x)+144-286.1x = 0 .
Question type: Equation
Solution:Original question:
| ( | 4771 10 | − | 2104 5 | x | ) | ( | 483 500 | − | 1 20 | x | ) | + | 144 | − | 2861 10 | x | = | 0 |
| Left side of the equation = | 4771 10 | ( | 483 500 | − | 1 20 | x | ) | − | 2104 5 | x | ( | 483 500 | − | 1 20 | x | ) | + | 144 | − | 2861 10 | x |
| = | 4771 10 | × | 483 500 | − | 4771 10 | × | 1 20 | x | − | 2104 5 | x | ( | 483 500 | − | 1 20 | x | ) | + | 144 | − | 2861 10 | x |
| = | 2304393 5000 | − | 4771 200 | x | − | 2104 5 | x | ( | 483 500 | − | 1 20 | x | ) | + | 144 | − | 2861 10 | x |
| = | 3024393 5000 | − | 61991 200 | x | − | 2104 5 | x | ( | 483 500 | − | 1 20 | x | ) |
| = | 3024393 5000 | − | 61991 200 | x | − | 2104 5 | x | × | 483 500 | + | 2104 5 | x | × | 1 20 | x |
| = | 3024393 5000 | − | 61991 200 | x | − | 254058 625 | x | + | 526 25 | x | x |
| = | 3024393 5000 | − | 3582239 5000 | x | + | 526 25 | x | x |
3024393 5000 | − | 3582239 5000 | x | + | 526 25 | x | x | = | 0 |
