Work: Find the solution of equation 4.7 = x/(60+x) .
Question type: Equation
Solution:Original question:
47 10 | = | x | ÷ | ( | 60 | + | x | ) |
| Multiply both sides of the equation by: | ( | 60 | + | x | ) |
47 10 | ( | 60 | + | x | ) | = | x |
47 10 | × | 60 | + | 47 10 | x | = | x |
| 282 | + | 47 10 | x | = | x |
Transposition :
47 10 | x | − | x | = | - | 282 |
Combine the items on the left of the equation:
37 10 | x | = | - | 282 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 282 | ÷ | 37 10 |
| = | - | 282 | × | 10 37 |
We obtained :
| x | = | - | 2820 37 |
Convert the result to decimal form :
| x | = | - 76.216216 |
