Work: Find the solution of equation 127.820*99.975%-x*100.025% = 0.5/10 .
Question type: Equation
Solution:Original question:
6391 50 | × | 3999 4000 | − | x | × | 4001 4000 | = | 1 2 | ÷ | 10 |
| Left side of the equation = | 25557609 200000 | − | x | × | 4001 4000 |
25557609 200000 | − | 4001 4000 | x | = | 1 2 | ÷ | 10 |
| Right side of the equation = | 1 20 |
25557609 200000 | − | 4001 4000 | x | = | 1 20 |
Transposition :
| - | 4001 4000 | x | = | 1 20 | − | 25557609 200000 |
Combine the items on the right of the equation:
| - | 4001 4000 | x | = | - | 25547609 200000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
25547609 200000 | = | 4001 4000 | 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 :
4001 4000 | x | = | 25547609 200000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 25547609 200000 | ÷ | 4001 4000 |
| = | 25547609 200000 | × | 4000 4001 |
| = | 25547609 50 | × | 1 4001 |
We obtained :
| x | = | 25547609 200050 |
Convert the result to decimal form :
| x | = | 127.706118 |
