(2+x)dy/dx=3y need help
den301095 [7]
(2+x) \frac{dy}{dx} =3y
\frac{1}{3y} dy= \frac{1}{2+x} dx
\int { \frac{1}{3y} } \, dy = \int { \frac{1}{2+x} } \, dx
\frac{1}{3}\ln(3y) = \ln(2+x) + C
(raise both to the power e): e^{ \frac{1}{3}\ln(3y)}=e^{\ln(k(2+x))}
(3y)^ \frac{1}{3} =k(2+x)
3y=k(2+x)^3
y= k(2+x)^3

< = 

then the sum of twice the number and 8
(2n +(-8)) = (2n - 8)

so we have :
