Work: Find the solution of equation （x-0.98）/x = 0.31111 .
Question type: Equation
Solution:Original question:
| ( | x | − | 49 50 | ) | ÷ | x | = | 31111 100000 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 49 50 | ) | = | 31111 100000 | x |
| x | − | 49 50 | = | 31111 100000 | x |
Transposition :
| x | − | 31111 100000 | x | = | 49 50 |
Combine the items on the left of the equation:
68889 100000 | x | = | 49 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 49 50 | ÷ | 68889 100000 |
| = | 49 50 | × | 100000 68889 |
| = | 49 | × | 2000 68889 |
We obtained :
| x | = | 98000 68889 |
Convert the result to decimal form :
| x | = | 1.422578 |
