Work: Find the solution of equation （61.7-x）1.1+0.73x = 65.5871 .
Question type: Equation
Solution:Original question:
| ( | 617 10 | − | x | ) | × | 11 10 | + | 73 100 | x | = | 655871 10000 |
| Left side of the equation = | 617 10 | × | 11 10 | − | x | × | 11 10 | + | 73 100 | x |
| = | 6787 100 | − | x | × | 11 10 | + | 73 100 | x |
| = | 6787 100 | − | 37 100 | x |
6787 100 | − | 37 100 | x | = | 655871 10000 |
Transposition :
| - | 37 100 | x | = | 655871 10000 | − | 6787 100 |
Combine the items on the right of the equation:
| - | 37 100 | x | = | - | 22829 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
22829 10000 | = | 37 100 | 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 :
37 100 | x | = | 22829 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 22829 10000 | ÷ | 37 100 |
| = | 22829 10000 | × | 100 37 |
| = | 617 100 | × | 1 |
We obtained :
| x | = | 617 100 |
Convert the result to decimal form :
| x | = | 6.17 |
