Work: Find the solution of equation -85493.52+74076.05/(1+x)+29238.5/(1+x)/(1+x) = 0 .
Question type: Equation
Solution:Original question:
| - | 2137338 25 | + | 1481521 20 | ÷ | ( | 1 | + | x | ) | + | 58477 2 | ÷ | ( | 1 | + | x | ) | ÷ | ( | 1 | + | x | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| - | 2137338 25 | ( | 1 | + | x | ) | + | 1481521 20 | + | 58477 2 | ÷ | ( | 1 | + | x | ) | = | 0 |
| - | 2137338 25 | × | 1 | − | 2137338 25 | x | + | 1481521 20 | + | 58477 2 | ÷ | ( | 1 | + | x | ) | = | 0 |
| - | 2137338 25 | − | 2137338 25 | x | + | 1481521 20 | + | 58477 2 | ÷ | ( | 1 | + | x | ) | = | 0 |
| - | 1141747 100 | − | 2137338 25 | x | + | 58477 2 | ÷ | ( | 1 | + | x | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| - | 1141747 100 | ( | 1 | + | x | ) | − | 2137338 25 | x | ( | 1 | + | x | ) | + | 58477 2 | = | 0 |
| - | 1141747 100 | × | 1 | − | 1141747 100 | x | − | 2137338 25 | x | ( | 1 | + | x | ) | + | 58477 2 | = | 0 |
| - | 1141747 100 | − | 1141747 100 | x | − | 2137338 25 | x | ( | 1 | + | x | ) | + | 58477 2 | = | 0 |
1782103 100 | − | 1141747 100 | x | − | 2137338 25 | x | ( | 1 | + | x | ) | = | 0 |
1782103 100 | − | 1141747 100 | x | − | 2137338 25 | x | × | 1 | − | 2137338 25 | x | x | = | 0 |
1782103 100 | − | 1141747 100 | x | − | 2137338 25 | x | − | 2137338 25 | x | x | = | 0 |
1782103 100 | − | 9691099 100 | x | − | 2137338 25 | x | x | = | 0 |
