Work: Find the solution of equation （x-63.1618）/（x+2） = 0.4976 .
Question type: Equation
Solution:Original question:
| ( | x | − | 315809 5000 | ) | ÷ | ( | x | + | 2 | ) | = | 311 625 |
| Multiply both sides of the equation by: | ( | x | + | 2 | ) |
| ( | x | − | 315809 5000 | ) | = | 311 625 | ( | x | + | 2 | ) |
| x | − | 315809 5000 | = | 311 625 | ( | x | + | 2 | ) |
| x | − | 315809 5000 | = | 311 625 | x | + | 311 625 | × | 2 |
| x | − | 315809 5000 | = | 311 625 | x | + | 622 625 |
Transposition :
| x | − | 311 625 | x | = | 622 625 | + | 315809 5000 |
Combine the items on the left of the equation:
314 625 | x | = | 622 625 | + | 315809 5000 |
Combine the items on the right of the equation:
314 625 | x | = | 64157 1000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 64157 1000 | ÷ | 314 625 |
| = | 64157 1000 | × | 625 314 |
| = | 64157 8 | × | 5 314 |
We obtained :
| x | = | 320785 2512 |
Convert the result to decimal form :
| x | = | 127.701035 |
