Evaluate the following limits :
`lim_(x rarr 0) (px + q)/(ax + b)`

Explanation

To evaluate the limit \( \lim_{x \to 0} \frac{px + q}{ax + b} \), we can follow these steps:

### Step 1: Substitute \( x = 0 \)
We start by substituting \( x = 0 \) directly into the expression \( \frac{px + q}{ax + b} \).

\[ \lim_{x \to 0} \frac{px + q}{ax + b} = \frac{p(0) + q}{a(0) + b} = \frac{q}{b} \]
