Work: Find the solution of equation 19.6078*（x-153）/x = 2 .
Question type: Equation
Solution:Original question:
98039 5000 | ( | x | − | 153 | ) | ÷ | x | = | 2 |
| Multiply both sides of the equation by: | x |
98039 5000 | ( | x | − | 153 | ) | = | 2 | x |
98039 5000 | x | − | 98039 5000 | × | 153 | = | 2 | x |
98039 5000 | x | − | 14999967 5000 | = | 2 | x |
Transposition :
98039 5000 | x | − | 2 | x | = | 14999967 5000 |
Combine the items on the left of the equation:
88039 5000 | x | = | 14999967 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 14999967 5000 | ÷ | 88039 5000 |
| = | 14999967 5000 | × | 5000 88039 |
| = | 14999967 | × | 1 88039 |
We obtained :
| x | = | 14999967 88039 |
Convert the result to decimal form :
| x | = | 170.378662 |
