Example 2
Solve.
Step 1. Use cross-multiplication to turn the rational equation into a polynomial equation.
Step 2. Simplify the equation, using the distributive property.
Step 3. Solve the equation.
Step 4. Check for extraneous solutions.
The original equation had excluded values 
, since neither of these are the solution, x = 12 is not an extraneous solution.
*Remember: you can always check your answers by plugging the solutions into the original equation.
