Work: Find the solution of equation -78928.4+62163.25/（1+x）+30316.76/(1+x)/(x+1) = 0 .
Question type: Equation
Solution:Original question:
| - | 394642 5 | + | 248653 4 | ÷ | ( | 1 | + | x | ) | + | 757919 25 | ÷ | ( | 1 | + | x | ) | ÷ | ( | x | + | 1 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| - | 394642 5 | ( | 1 | + | x | ) | + | 248653 4 | + | 757919 25 | ÷ | ( | x | + | 1 | ) | = | 0 |
| - | 394642 5 | × | 1 | − | 394642 5 | x | + | 248653 4 | + | 757919 25 | ÷ | ( | x | + | 1 | ) | = | 0 |
| - | 394642 5 | − | 394642 5 | x | + | 248653 4 | + | 757919 25 | ÷ | ( | x | + | 1 | ) | = | 0 |
| - | 335303 20 | − | 394642 5 | x | + | 757919 25 | ÷ | ( | x | + | 1 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | x | + | 1 | ) |
| - | 335303 20 | ( | x | + | 1 | ) | − | 394642 5 | x | ( | x | + | 1 | ) | + | 757919 25 | = | 0 |
| - | 335303 20 | x | − | 335303 20 | × | 1 | − | 394642 5 | x | ( | x | + | 1 | ) | + | 757919 25 | = | 0 |
| - | 335303 20 | x | − | 335303 20 | − | 394642 5 | x | ( | x | + | 1 | ) | + | 757919 25 | = | 0 |
| - | 335303 20 | x | + | 1355161 100 | − | 394642 5 | x | ( | x | + | 1 | ) | = | 0 |
| - | 335303 20 | x | + | 1355161 100 | − | 394642 5 | x | x | − | 394642 5 | x | × | 1 | = | 0 |
| - | 335303 20 | x | + | 1355161 100 | − | 394642 5 | x | x | − | 394642 5 | x | = | 0 |
| - | 1913871 20 | x | + | 1355161 100 | − | 394642 5 | x | x | = | 0 |
