Solving by finding a common denominator.
When to do this:
• When you have more than 1 term on either side of the equal sign.
How to do this:
• Look back to 9.4 to remember how to get a common denominator
1. Get a common denominator across all terms
2. Multiply every term by the common denominator, canceling all of the denominators
3. Solve like a normal equation.
