Work: Find the solution of equation X-0.2X-0.05X-3 = 13.23+0.2*13.23 .
Question type: Equation
Solution:Original question:
| X | − | 1 5 | X | − | 1 20 | X | − | 3 | = | 1323 100 | + | 1 5 | × | 1323 100 |
| Left side of the equation = | 3 4 | X | − | 3 |
3 4 | X | − | 3 | = | 1323 100 | + | 1 5 | × | 1323 100 |
| Right side of the equation = | 1323 100 | + | 1323 500 |
| = | 3969 250 |
3 4 | X | − | 3 | = | 3969 250 |
Transposition :
3 4 | X | = | 3969 250 | + | 3 |
Combine the items on the right of the equation:
3 4 | X | = | 4719 250 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 4719 250 | ÷ | 3 4 |
| = | 4719 250 | × | 4 3 |
| = | 1573 125 | × | 2 |
We obtained :
| X | = | 3146 125 |
Convert the result to decimal form :
| X | = | 25.168 |
