$= \frac{8}{3x}$
1) Find a common denominator: Multiply the first fraction by 3/3 and leave the second fraction unchanged as you already can form a common denominator of $6x$ between the two fractions. 2) Add the fractions $= \frac{3}{2x} + \frac{7}{6x}$ $= \frac{3(3)}{6x} + \frac{7}{6x}$ $= \frac{9}{6x} + \frac{7}{6x}$ $= \frac{16}{6x}$ $= \frac{8}{3x}$
