Work: Find the solution of equation 100 = （0.83-0.487）/（x-0.83）29000 .
Question type: Equation
Solution:Original question:
| 100 | = | ( | 83 100 | − | 487 1000 | ) | ÷ | ( | x | − | 83 100 | ) | × | 29000 |
| Multiply both sides of the equation by: | ( | x | − | 83 100 | ) |
| 100 | ( | x | − | 83 100 | ) | = | ( | 83 100 | − | 487 1000 | ) | × | 29000 |
| 100 | x | − | 100 | × | 83 100 | = | ( | 83 100 | − | 487 1000 | ) | × | 29000 |
| 100 | x | − | 100 | × | 83 100 | = | 83 100 | × | 29000 | − | 487 1000 | × | 29000 |
| 100 | x | − | 83 | = | 24070 | − | 14123 |
| 100 | x | − | 83 | = | 9947 |
Transposition :
| 100 | x | = | 9947 | + | 83 |
Combine the items on the right of the equation:
| 100 | x | = | 10030 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 10030 | ÷ | 100 |
| = | 10030 | × | 1 100 |
| = | 1003 | × | 1 10 |
We obtained :
| x | = | 1003 10 |
Convert the result to decimal form :
| x | = | 100.3 |
