Work: Find the solution of equation X-0.2X-0.05X-3 = 13.95+0.2*13.95 .
Question type: Equation
Solution:Original question:
| X | − | 1 5 | X | − | 1 20 | X | − | 3 | = | 279 20 | + | 1 5 | × | 279 20 |
| Left side of the equation = | 3 4 | X | − | 3 |
3 4 | X | − | 3 | = | 279 20 | + | 1 5 | × | 279 20 |
| Right side of the equation = | 279 20 | + | 279 100 |
| = | 837 50 |
3 4 | X | − | 3 | = | 837 50 |
Transposition :
3 4 | X | = | 837 50 | + | 3 |
Combine the items on the right of the equation:
3 4 | X | = | 987 50 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 987 50 | ÷ | 3 4 |
| = | 987 50 | × | 4 3 |
| = | 329 25 | × | 2 |
We obtained :
| X | = | 658 25 |
Convert the result to decimal form :
| X | = | 26.32 |
