Answer:
D. [tex] \bold{\frac{2(b - 1)}{ab} }[/tex]
Step-by-step explanation:
[tex] \frac{3}{a} - \frac{2 + b}{ab} \\ \\ = \frac{3b}{ab} - \frac{2 + b}{ab} \\ \\ = \frac{3b - (2 + b)}{ab} \\ \\ = \frac{3b - 2 - b}{ab} \\ \\ = \frac{2b - 2}{ab} \\ \\ \purple{ \bold{\frac{3}{a} - \frac{2 + b}{ab}} }\pink{= } \red{ \bold{\frac{2(b - 1)}{ab} }}[/tex]
