Q73. Let $\int \frac { 2 - \tan x } { 3 + \tan x } \mathrm {~d} x = \frac { 1 } { 2 } \left( \alpha x + \log _ { \mathrm { e } } | \beta \sin x + \gamma \cos x | \right) + C$, where $C$ is the constant of integration. Then $\alpha + \frac { \gamma } { \beta }$ is equal to :\\
(1) 7\\
(2) 4\\
(3) 1\\
(4) 3
