In this type of equation, simply use the tools of mathematical operations like addition, subtraction, multiplication or division to eliminate the numbers in the equation and also maintaining the equality by using the proper numbers and get the result.

Since, the equation is $9n+64=-144+17n$.

Here, to simplify this equation, Take the variable in left hand side and the numbers in right hand side and do mathematical operations to get the solution.

$\begin{array}{l}9n+64=鈭�144+17n\\ 9n鈭�17n=鈭�144鈭�64\\ \cancel{鈭�}8n=\cancel{鈭�}208\\ n=\frac{208}{8}\\ n=26\end{array}$

Since, the solution is, $n=26$and the equation is $9n+64=-144+17n$.

So,

Put $n=26$in equation,

$\begin{array}{l}Left\text{鈥夆赌�}Hand\text{鈥�}Side:\\ =9n+64\\ =9\left(26\right)+64\\ =234+64\\ =298\\ Right\text{鈥�}Hand\text{鈥�}Side\\ =鈭�144+17n\\ =鈭�144+17\left(26\right)\\ =鈭�144+442\\ =298\end{array}$

It holds the equation.

So, the solution $n=26$correctly holds the equation.
