[ 1/1 Equation]
Work: Find the solution of equation X-X*(1+17%)*9%-X*3%-X*10% = 15250.97 .
Question type: Equation
Solution:Original question:
| X | − | X | ( | 1 | + | 17 100 | ) | × | 9 100 | − | X | × | 3 100 | − | X | × | 10 100 | = | 1525097 100 |
| Left side of the equation = | 87 100 | X | − | X | ( | 1 | + | 17 100 | ) | × | 9 100 |
87 100 | X | − | X | ( | 1 | + | 17 100 | ) | × | 9 100 | = | 1525097 100 |
| Left side of the equation = | 87 100 | X | − | X | × | 1 | × | 9 100 | − | X | × | 17 100 | × | 9 100 |
| = | 87 100 | X | − | X | × | 9 100 | − | X | × | 153 10000 |
| = | 7647 10000 | X |
7647 10000 | X | = | 1525097 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 1525097 100 | ÷ | 7647 10000 |
| = | 1525097 100 | × | 10000 7647 |
| = | 1525097 | × | 100 7647 |
We obtained :
| X | = | 152509700 7647 |
Convert the result to decimal form :
| X | = | 19943.729567 |
