Work: Find the solution of equation 100+100/(1+x) = 103.01 .
Question type: Equation
Solution:Original question:
| 100 | + | 100 | ÷ | ( | 1 | + | x | ) | = | 10301 100 |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| 100 | ( | 1 | + | x | ) | + | 100 | = | 10301 100 | ( | 1 | + | x | ) |
| 100 | × | 1 | + | 100 | x | + | 100 | = | 10301 100 | ( | 1 | + | x | ) |
| 100 | × | 1 | + | 100 | x | + | 100 | = | 10301 100 | × | 1 | + | 10301 100 | x |
| 100 | + | 100 | x | + | 100 | = | 10301 100 | + | 10301 100 | x |
| 200 | + | 100 | x | = | 10301 100 | + | 10301 100 | x |
Transposition :
| 100 | x | − | 10301 100 | x | = | 10301 100 | − | 200 |
Combine the items on the left of the equation:
| - | 301 100 | x | = | 10301 100 | − | 200 |
Combine the items on the right of the equation:
| - | 301 100 | x | = | - | 9699 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
9699 100 | = | 301 100 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
301 100 | x | = | 9699 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 9699 100 | ÷ | 301 100 |
| = | 9699 100 | × | 100 301 |
| = | 9699 | × | 1 301 |
We obtained :
| x | = | 9699 301 |
Convert the result to decimal form :
| x | = | 32.222591 |
