Work: Find the solution of equation 0.727x+56.23/1.25-0.272x+52.3/1000 = x .
Question type: Equation
Solution:Original question:
727 1000 | x | + | 5623 100 | ÷ | 5 4 | − | 34 125 | x | + | 523 10 | ÷ | 1000 | = | x |
| Left side of the equation = | 727 1000 | x | + | 5623 125 | − | 34 125 | x | + | 523 10000 |
| = | 91 200 | x | + | 450363 10000 |
91 200 | x | + | 450363 10000 | = | x |
Transposition :
91 200 | x | − | x | = | - | 450363 10000 |
Combine the items on the left of the equation:
| - | 109 200 | x | = | - | 450363 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
450363 10000 | = | 109 200 | 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 :
109 200 | x | = | 450363 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 450363 10000 | ÷ | 109 200 |
| = | 450363 10000 | × | 200 109 |
| = | 450363 50 | × | 1 109 |
We obtained :
| x | = | 450363 5450 |
Convert the result to decimal form :
| x | = | 82.635413 |
