Consider the initial value problem:

$7x\frac{dy}{dx}=21y{x}^{-3},y(1)=\frac{83}{42}$

a$.$ Use an integration factor to solve this linear DE and enter in the general solution. Use $C$ for the arbitrary constant.

$y=(1)$

b$.$ Find the particular solution which satisfies the initial condition.

$y=$
