Work: Find the solution of equation (x-1.9)/x = 0.33333 .
Question type: Equation
Solution:Original question:
| ( | x | − | 19 10 | ) | ÷ | x | = | 33333 100000 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 19 10 | ) | = | 33333 100000 | x |
| x | − | 19 10 | = | 33333 100000 | x |
Transposition :
| x | − | 33333 100000 | x | = | 19 10 |
Combine the items on the left of the equation:
66667 100000 | x | = | 19 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 19 10 | ÷ | 66667 100000 |
| = | 19 10 | × | 100000 66667 |
| = | 19 | × | 10000 66667 |
We obtained :
| x | = | 190000 66667 |
Convert the result to decimal form :
| x | = | 2.849986 |
