Question from deanna, a student:

x      x
-- + -- = 8
9     3
need help with showing work and answer

Hi Deanna,

The difference between this problem and the earlier question you sent is that this problem involves fractions. I would multiple both sides of this equation by 9 and the fractions will be eliminated. I chose 9 because it is the least common denominator of the two fractions.

Once the fractions are eliminated you can use the method that Sue illustrated in response to your earlier question.
