Work: Find the solution of equation （x-63.1618）/（x+2） = 0.4460 .
Question type: Equation
Solution:Original question:
| ( | x | − | 315809 5000 | ) | ÷ | ( | x | + | 2 | ) | = | 223 500 |
| Multiply both sides of the equation by: | ( | x | + | 2 | ) |
| ( | x | − | 315809 5000 | ) | = | 223 500 | ( | x | + | 2 | ) |
| x | − | 315809 5000 | = | 223 500 | ( | x | + | 2 | ) |
| x | − | 315809 5000 | = | 223 500 | x | + | 223 500 | × | 2 |
| x | − | 315809 5000 | = | 223 500 | x | + | 223 250 |
Transposition :
| x | − | 223 500 | x | = | 223 250 | + | 315809 5000 |
Combine the items on the left of the equation:
277 500 | x | = | 223 250 | + | 315809 5000 |
Combine the items on the right of the equation:
277 500 | x | = | 320269 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 320269 5000 | ÷ | 277 500 |
| = | 320269 5000 | × | 500 277 |
| = | 320269 10 | × | 1 277 |
We obtained :
| x | = | 320269 2770 |
Convert the result to decimal form :
| x | = | 115.620578 |
