Evaluate the following limit: `underset( x rarr 0) ( "lim")(a x+b)/(c x+d),\ d!=0`

Explanation

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

### Step 1: Substitute \(x = 0\)
We start by substituting \(x = 0\) directly into the expression.

\[ \lim_{x \to 0} \frac{ax + b}{cx + d} = \frac{a(0) + b}{c(0) + d} = \frac{b}{d} \]
