Work: Find the solution of equation （X-1602.6-5000）*0.3 = X-8572.05-1602.6 .
Question type: Equation
Solution:Original question:
| ( | X | − | 8013 5 | − | 5000 | ) | × | 3 10 | = | X | − | 171441 20 | − | 8013 5 |
| Left side of the equation = | X | × | 3 10 | − | 8013 5 | × | 3 10 | − | 5000 | × | 3 10 |
| = | X | × | 3 10 | − | 24039 50 | − | 1500 |
| = | 3 10 | X | − | 99039 50 |
3 10 | X | − | 99039 50 | = | X | − | 171441 20 | − | 8013 5 |
| Right side of the equation = | X | − | 203493 20 |
3 10 | X | − | 99039 50 | = | X | − | 203493 20 |
Transposition :
3 10 | X | − | X | = | - | 203493 20 | + | 99039 50 |
Combine the items on the left of the equation:
| - | 7 10 | X | = | - | 203493 20 | + | 99039 50 |
Combine the items on the right of the equation:
| - | 7 10 | X | = | - | 819387 100 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
819387 100 | = | 7 10 | X |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
7 10 | X | = | 819387 100 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 819387 100 | ÷ | 7 10 |
| = | 819387 100 | × | 10 7 |
| = | 819387 10 | × | 1 7 |
We obtained :
| X | = | 819387 70 |
Convert the result to decimal form :
| X | = | 11705.528571 |
