Answer
LCD; $12$
Work Step by Step
The given equation has a denominator of 4 on its left side and a denominator of 3 on its right
The Least Common Denominator (LCD) of $4$ and $3$ is $12$.
Note that when 12 is multiplied on both sides of the equation, the denominators will be eliminated. This allows an easier way of solving the equation since there will be no denominators to deal with.
Thus, the missing expressions in the given statement are:
LCD;
$12$
