Work: Find the solution of equation x+(x*13%) = 100 .
Question type: Equation
Solution:Original question:
| x | + | ( | x | × | 13 100 | ) | = | 100 |
| Left side of the equation = | x | + | x | × | 13 100 |
| = | 113 100 | x |
113 100 | x | = | 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 100 | ÷ | 113 100 |
| = | 100 | × | 100 113 |
We obtained :
| x | = | 10000 113 |
Convert the result to decimal form :
| x | = | 88.495575 |
