Work: Find the solution of equation 8224+257000/125-x-56x/1000 = x .
Question type: Equation
Solution:Original question:
| 8224 | + | 257000 | ÷ | 125 | − | x | − | 56 | x | ÷ | 1000 | = | x |
| Left side of the equation = | 8224 | + | 2056 | − | x | − | 7 125 | x |
| = | 10280 | − | 132 125 | x |
| 10280 | − | 132 125 | x | = | x |
Transposition :
| - | 132 125 | x | − | x | = | - | 10280 |
Combine the items on the left of the equation:
| - | 257 125 | x | = | - | 10280 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| 10280 | = | 257 125 | 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 :
257 125 | x | = | 10280 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 10280 | ÷ | 257 125 |
| = | 10280 | × | 125 257 |
We obtained :
| x | = | 1285000 257 |
By reducing fraction, we can get:
| x | = | 5000 |
