Work: Find the solution of equation X-0.1X-0.05X-3 = 556.9+0.15*556.9 .
Question type: Equation
Solution:Original question:
| X | − | 1 10 | X | − | 1 20 | X | − | 3 | = | 5569 10 | + | 3 20 | × | 5569 10 |
| Left side of the equation = | 17 20 | X | − | 3 |
17 20 | X | − | 3 | = | 5569 10 | + | 3 20 | × | 5569 10 |
| Right side of the equation = | 5569 10 | + | 16707 200 |
| = | 128087 200 |
17 20 | X | − | 3 | = | 128087 200 |
Transposition :
17 20 | X | = | 128087 200 | + | 3 |
Combine the items on the right of the equation:
17 20 | X | = | 128687 200 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 128687 200 | ÷ | 17 20 |
| = | 128687 200 | × | 20 17 |
| = | 128687 10 | × | 1 17 |
We obtained :
| X | = | 128687 170 |
Convert the result to decimal form :
| X | = | 756.982353 |
