Work: Find the solution of equation X÷（X+555.56） = 3% .
Question type: Equation
Solution:Original question:
| X | ÷ | ( | X | + | 13889 25 | ) | = | 3 100 |
| Multiply both sides of the equation by: | ( | X | + | 13889 25 | ) |
| X | = | 3 100 | ( | X | + | 13889 25 | ) |
| X | = | 3 100 | X | + | 3 100 | × | 13889 25 |
| X | = | 3 100 | X | + | 41667 2500 |
Transposition :
| X | − | 3 100 | X | = | 41667 2500 |
Combine the items on the left of the equation:
97 100 | X | = | 41667 2500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 41667 2500 | ÷ | 97 100 |
| = | 41667 2500 | × | 100 97 |
| = | 41667 25 | × | 1 97 |
We obtained :
| X | = | 41667 2425 |
Convert the result to decimal form :
| X | = | 17.182268 |
