Let's evaluate each expression step by step.
**Question 1:** Evaluate the expression \(2a - 3 + b\) when \(a = 4\) and \(b = 5\).
Substituting the values into the expression:
\[
2(4) - 3 + 5
\]
Calculate \(2(4)\):
\[
8 - 3 + 5
\]
Now subtract 3 from 8:
\[
5 + 5 = 10
\]
So the answer is **10**.

**Question 2:** Evaluate \(24 - \frac{y}{4}\) when \(y = 12\).
Substituting the value of \(y\):
\[
24 - \frac{12}{4}
\]
Calculate \(\frac{12}{4}\):
\[
24 - 3
\]
Now subtract 3 from 24:
\[
21
\]
So the answer is **21**.
