Given:


-9(n+4)=-5n-(4n+36)


\begin{gathered} \text{take, Left hand side , -9(n+4)} \\ \text{ -9(n+4)}=-9n+(-9)\cdot4 \\ =-9n-36\ldots\text{.}\mathrm{}(1) \end{gathered}

Now, take right hand side of the equation,


\begin{gathered} -5n-(4n+36)=-5n-4n-36 \\ =-9n-36\ldots\text{.}(2) \end{gathered}

From equation (1) and (2) it is concluded that,


\begin{gathered} \text{left hand side=right hand side} \\ -9(n+4)=-5n-(4n+36) \end{gathered}
