Work: Find the solution of equation -78928.4+76183.66/(1+x)+41308.35/（1+x）/（1+x） = 0 .
Question type: Equation
Solution:Original question:
| - | 394642 5 | + | 3809183 50 | ÷ | ( | 1 | + | x | ) | + | 826167 20 | ÷ | ( | 1 | + | x | ) | ÷ | ( | 1 | + | x | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| - | 394642 5 | ( | 1 | + | x | ) | + | 3809183 50 | + | 826167 20 | ÷ | ( | 1 | + | x | ) | = | 0 |
| - | 394642 5 | × | 1 | − | 394642 5 | x | + | 3809183 50 | + | 826167 20 | ÷ | ( | 1 | + | x | ) | = | 0 |
| - | 394642 5 | − | 394642 5 | x | + | 3809183 50 | + | 826167 20 | ÷ | ( | 1 | + | x | ) | = | 0 |
| - | 137237 50 | − | 394642 5 | x | + | 826167 20 | ÷ | ( | 1 | + | x | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| - | 137237 50 | ( | 1 | + | x | ) | − | 394642 5 | x | ( | 1 | + | x | ) | + | 826167 20 | = | 0 |
| - | 137237 50 | × | 1 | − | 137237 50 | x | − | 394642 5 | x | ( | 1 | + | x | ) | + | 826167 20 | = | 0 |
| - | 137237 50 | − | 137237 50 | x | − | 394642 5 | x | ( | 1 | + | x | ) | + | 826167 20 | = | 0 |
3856361 100 | − | 137237 50 | x | − | 394642 5 | x | ( | 1 | + | x | ) | = | 0 |
3856361 100 | − | 137237 50 | x | − | 394642 5 | x | × | 1 | − | 394642 5 | x | x | = | 0 |
3856361 100 | − | 137237 50 | x | − | 394642 5 | x | − | 394642 5 | x | x | = | 0 |
3856361 100 | − | 4083657 50 | x | − | 394642 5 | x | x | = | 0 |
