When solving an equation using the Distributive Property that involves distributing fractions, usually the first step is to multiply by the LCD to eliminate the fractions in order to simplify computation. Is it necessary to do this to solve \(\large\frac{1}{2}\small(4\text{x} + 6) = \large\frac{1}{3}\small(9\text{x} - 24)\)? Why or why not?
