Answer the question.Without multiplying by the least common denominator and solving, explain why the rational equation 
has no solution. (Hint: Examine both numerators and denominators carefully.)
What will be an ideal response?
Since the denominators are the same, the numerators must be the same. Then x = 3; but this value of x makes the denominators 0, so the equation has no solution.
