This document provides instructions on how to solve rational equations. It explains that you first find the least common denominator, then multiply both sides by the LCD to eliminate fractions. You then simplify the equation and solve for the variable. To check your work, plug your solution back in and see if both sides are equal. The document includes examples of solving two practice rational equations for the variables N and W.

1. Intro Video

2. UNIT 8-6 Solving Rational Equations and Simplifying Expressions

3. Section 1!!! Here, you will learn how to solve rational equations!!!

4. How To Solve To start, you first need to find the Least Common Denominator (or LCD)! LCD= (28)(Z+2)

5. How To Solve You then multiply by the LCD, to get rid of the denominator.

6. How To Solve Now, you just simplify the equation and solve for X.

7. How To Check First, you plug in the amount you got for the variable, and simplify.

8. How To Check Then, you combine like terms, and make the 2 fractions on the right side have a common denominator, so they can be combined.

9. How To Check Finally, you combine like terms again… and simplify. If both sides are equal to each other, then your answer is correct, if not, you may want to go back and check your work.

11. Practice #1 In the equation (1/n+2)+(1/n-2)=(3/n2-4), what is N?

12. Practice #1 In the equation (1/n+2)+(1/n-2)=(3/n2-4), what is N?

13. Practice #1 In the equation (1/n+2)+(1/n-2)=(3/n2-4), what is N?

14. Did You know It? The correct answer was… N=3/2! Your work should have looked something like this.

15. Practice #2 In the equation… What is W?

16. Practice #2 In the equation… What is W?

17. Practice #2 In the equation… What is W?

18. Did You Know It? The correct answer was…W=-2! Your work should have looked like this.
