Work: Find the solution of equation 0.017 = （x-478.1）/478.1 .
Question type: Equation
Solution:Original question:
17 1000 | = | ( | x | − | 4781 10 | ) | ÷ | 4781 10 |
| Right side of the equation = | x | × | 10 4781 | − | 4781 10 | × | 10 4781 |
| = | x | × | 10 4781 | − | 1 |
17 1000 | = | 10 4781 | x | − | 1 |
Transposition :
| - | 10 4781 | x | = | - | 1 | − | 17 1000 |
Combine the items on the right of the equation:
| - | 10 4781 | x | = | - | 1017 1000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
1017 1000 | = | 10 4781 | 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 :
10 4781 | x | = | 1017 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1017 1000 | ÷ | 10 4781 |
| = | 1017 1000 | × | 4781 10 |
We obtained :
| x | = | 4862277 10000 |
Convert the result to decimal form :
| x | = | 486.2277 |
