Work: Find the solution of equation (x-62.485)/(x+1) = 0.39 .
Question type: Equation
Solution:Original question:
| ( | x | − | 12497 200 | ) | ÷ | ( | x | + | 1 | ) | = | 39 100 |
| Multiply both sides of the equation by: | ( | x | + | 1 | ) |
| ( | x | − | 12497 200 | ) | = | 39 100 | ( | x | + | 1 | ) |
| x | − | 12497 200 | = | 39 100 | ( | x | + | 1 | ) |
| x | − | 12497 200 | = | 39 100 | x | + | 39 100 | × | 1 |
| x | − | 12497 200 | = | 39 100 | x | + | 39 100 |
Transposition :
| x | − | 39 100 | x | = | 39 100 | + | 12497 200 |
Combine the items on the left of the equation:
61 100 | x | = | 39 100 | + | 12497 200 |
Combine the items on the right of the equation:
61 100 | x | = | 503 8 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 503 8 | ÷ | 61 100 |
| = | 503 8 | × | 100 61 |
| = | 503 2 | × | 25 61 |
We obtained :
| x | = | 12575 122 |
Convert the result to decimal form :
| x | = | 103.07377 |
