Solving Rational Equations

This video tutorial demonstrates a method for solving rational equations by finding a common denominator, rewriting fractions, clearing fractions from the equation, and solving the simplified equation. The solution is verified by substituting back into the original equation.

What is the first step in the new method for solving rational equations?

• Add all fractions together

• Subtract the smallest fraction from the largest

• Find a common denominator for all terms

• Multiply all terms by the largest denominator

What is the least common denominator for the denominators 3, 4, 6, 2, and 12?

• 6

• 24

• 18

• 12
