Work: Find the solution of equation x/(x+2) = 0.0796 .
Question type: Equation
Solution:Original question:
| x | ÷ | ( | x | + | 2 | ) | = | 199 2500 |
| Multiply both sides of the equation by: | ( | x | + | 2 | ) |
| x | = | 199 2500 | ( | x | + | 2 | ) |
| x | = | 199 2500 | x | + | 199 2500 | × | 2 |
| x | = | 199 2500 | x | + | 199 1250 |
Transposition :
| x | − | 199 2500 | x | = | 199 1250 |
Combine the items on the left of the equation:
2301 2500 | x | = | 199 1250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 199 1250 | ÷ | 2301 2500 |
| = | 199 1250 | × | 2500 2301 |
| = | 199 | × | 2 2301 |
We obtained :
| x | = | 398 2301 |
Convert the result to decimal form :
| x | = | 0.172968 |
