How to solve a basic rational expression with x in the denominator twice

The video tutorial explains how to identify the least common denominator (LCD) when dealing with fractions. It demonstrates rewriting numbers as fractions to find the LCD, multiplying all terms by the LCD to simplify the equation, and solving the resulting equation. The process is broken down into clear steps, making it easy to follow and understand.

What is the LCD when 2 is rewritten as a fraction?

• 6

• X

• 2

• 1

Why do we multiply each term by the LCD?

• To add more terms

• To make the equation longer

• To simplify the equation

• To change the equation completely

What is the result of multiplying each term by the LCD in this example?

• 5 + 2X = 6

• X = 6

• 2X = 5

• 5X = 2

What is the first step in solving the equation 5 + 2X = 6?

• Add 5

• Divide by 2

• Multiply by 2

• Subtract 5

What is the final value of X in the equation?

• 1

• 1/2

• 5

• 2
