Solving Equations Involving Fractions

The video tutorial explains how to solve an equation for n by first clearing fractions and denominators. It begins by multiplying both sides by n to eliminate the fraction, then clears the denominator by multiplying by n-2. Finally, it solves for n by simplifying the equation, resulting in n equals four.

What is the purpose of multiplying both sides of the equation by n/n?

• To change the equation's variables

• To eliminate the fraction on the left side

• To simplify the right side of the equation

• To add a new term to the equation
