Q.3 (C) (ii) Solve the following differential equations \(\frac{dy}{dx}+y=5\)

Solution: \(\frac{dy}{dx}+y=5\)
Given equation is a linear differential equation.
Here \(P=\)[ ] \(Q=5\)
\(\therefore\) I.F. \(=e^{\int p\,dx}\)
\(\therefore\) I.F. \(=\)[ ]
The solution of given linear differential equation is
By formula [ ]
\(\therefore y\cdot e^x=\int 5\cdot e^x\,dx+c\)
\(\therefore\) [ ]

Answer: Boxes: \(P=1\); I.F. \(=e^x\); \(y\cdot(\text{I.F.})=\int Q\cdot(\text{I.F.})\,dx+c\); \(y e^x=5e^x+c\)

Comparing with \(\frac{dy}{dx}+Py=Q\): \(P=\boxed{1}\), \(Q=5\).

I.F. \(=e^{\int 1\,dx}=\boxed{e^x}\).

By formula \(\boxed{y\cdot(\text{I.F.})=\int Q\cdot(\text{I.F.})\,dx+c}\):

\(y\cdot e^x=\int 5e^x\,dx+c\)

\(\therefore\boxed{y e^x=5e^x+c}\), i.e. \(y=5+ce^{-x}\).
