1. Berilgan funksiya: $$ f(x)=3x-1 $$.

2. $$ f(x+3) $$ ni hisoblaymiz:
   $$
   f(x+3)=3(x+3)-1=3x+9-1=3x+8.
   $$

3. $$ f(x+3)=5 $$ tenglamasini yechamiz:
   $$
   3x+8=5.
   $$

4. Tenglamadan $$ x $$ ni topamiz:
   $$
   3x=5-8=-3 \quad \Rightarrow \quad x=-1.
   $$

Natija: $$ x=-1 $$ (Variant A).
Natija: $$ x=-1 $$, variant A.
