Solving an equation with parentheses

The video tutorial explains how to solve an equation with two variables by simplifying expressions, distributing negative signs, combining like terms, and solving the resulting equation. The process involves using the order of operations and properties of equality to find the value of N. The tutorial emphasizes the importance of checking solutions, although it is not demonstrated in the video.

What is the final solution for the variable N, and how is it derived?

Why is it important to verify the solution after solving the equation?
