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

Why is it important that n does not equal zero when multiplying by n/n?

• Because it would add a new variable

• Because it would change the equation's solution

• Because it would simplify the equation

• Because it would make the equation undefined

What is achieved by multiplying both sides of the equation by n minus two?

• It changes the equation's solution

• It clears the denominator of n minus two

• It adds a new term to the equation

• It simplifies the right side of the equation

What is the result of subtracting two n from both sides of the equation?

• The equation becomes more complex

• A new variable is introduced

• The equation is simplified to negative n equals negative four

• The equation becomes undefined

What is the final value of n after solving the equation?

• n equals four

• n equals zero

• n equals negative four

• n equals two
