By rewriting the equation and eliminating fractions, the instructor demonstrates how to isolate the variable X. The tutorial concludes with a solved equation and an invitation for viewers to ask questions.

What is a common mistake students make when trying to solve the equation X + 2 / y = 2?

• They divide both sides by X.

• They incorrectly subtract 2 from both sides.

• They multiply both sides by 2.

• They forget to add 2 to both sides.

How can you eliminate a fraction in an equation like X + 2 / y = 2?

• Multiply both sides by the denominator.

• Add the denominator to both sides.

• Divide both sides by the numerator.

• Subtract the numerator from both sides.

What happens to the equation X + 2 / y = 2 when you multiply both sides by y?

• The equation becomes X + y = 2.

• The equation becomes X = 2 / y.

• The equation becomes X = 2y + 2.

• The equation becomes X + 2 = 2y.

After eliminating the fraction, what is the next step to solve for X in the equation X + 2 = 2y?

• Subtract 2 from both sides.

• Multiply both sides by 2.

• Divide both sides by y.

• Add 2 to both sides.

What is the final expression for X after solving the equation X + 2 = 2y?

• X = y - 2

• X = 2 / y

• X = 2y - 2

• X = 2y + 2
