Work: Find the solution of equation X-0.2X-0.05X-2 = 21.3+0.2*21.3 .
Question type: Equation
Solution:Original question:
| X | − | 1 5 | X | − | 1 20 | X | − | 2 | = | 213 10 | + | 1 5 | × | 213 10 |
| Left side of the equation = | 3 4 | X | − | 2 |
3 4 | X | − | 2 | = | 213 10 | + | 1 5 | × | 213 10 |
| Right side of the equation = | 213 10 | + | 213 50 |
| = | 639 25 |
3 4 | X | − | 2 | = | 639 25 |
Transposition :
3 4 | X | = | 639 25 | + | 2 |
Combine the items on the right of the equation:
3 4 | X | = | 689 25 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 689 25 | ÷ | 3 4 |
| = | 689 25 | × | 4 3 |
We obtained :
| X | = | 2756 75 |
Convert the result to decimal form :
| X | = | 36.746667 |
