Answer
$2$
Work Step by Step
To add rational expressions with the same denominator,
add numerators and place the sum over the common denominator.
If possible, factor and simplify the result.
---
$\displaystyle \frac{3x+2}{3x+4}+\frac{3x+6}{3x+4} = \displaystyle \frac{3x+2+3x+6}{3x+4}$
$= \displaystyle \frac{6x+8}{3x+4}$
$= \displaystyle \frac{2(3x+4)}{(3x+4)}\qquad$... reduce the common factor
$= \displaystyle \frac{2}{1}=2$
