Answer
Explanation:
Step1: Use substitution method
Let $u = 3 - x$, then $du=-dx$.
Step2: Rewrite the integral
The integral $\int\frac{1}{3 - x}dx$ becomes $-\int\frac{1}{u}du$.
Step3: Integrate $\frac{1}{u}$
We know that $\int\frac{1}{u}du=\ln|u|+C$. So $-\int\frac{1}{u}du =-\ln|u|+C$.
Step4: Substitute back $u = 3 - x$
We get $-\ln|3 - x|+C$.
Answer:
$-\ln|3 - x|+C$
