Let
, so that
:

Now the ODE is separable, and we have

Integrating both sides gives

For the integral on the left, rewrite the integrand as

Then

and so


Given that
, we find

so that the particular solution to this IVP is

Ok so... Let x be 2.1
x = 2.1 / (3/10)
multiply both the numerator and denominator by 10 which gives
x = 21/3 SO the answer is......
x = 7 Yay!!! Have a god day
