Work: Find the solution of equation 610/1235 = x/（x+10%） .
Question type: Equation
Solution:Original question:
| 610 | ÷ | 1235 | = | x | ÷ | ( | x | + | 10 100 | ) |
| Multiply both sides of the equation by: | ( | x | + | 10 100 | ) |
| 610 | ÷ | 1235 | × | ( | x | + | 10 100 | ) | = | x |
| 610 | ÷ | 1235 | × | x | + | 610 | ÷ | 1235 | × | 10 100 | = | x |
122 247 | x | + | 61 1235 | = | x |
Transposition :
122 247 | x | − | x | = | - | 61 1235 |
Combine the items on the left of the equation:
| - | 125 247 | x | = | - | 61 1235 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
61 1235 | = | 125 247 | 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 :
125 247 | x | = | 61 1235 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 61 1235 | ÷ | 125 247 |
| = | 61 1235 | × | 247 125 |
| = | 61 5 | × | 1 125 |
We obtained :
| x | = | 61 625 |
Convert the result to decimal form :
| x | = | 0.0976 |
