Answer 1

To evaluate the expression \( 2a - 3 + b \) when \( a = 4 \) and \( b = 5 \):

1. Substitute \( a \) and \( b \) into the expression:
\[
2(4) - 3 + 5
\]

2. Calculate \( 2(4) \):
\[
2 \times 4 = 8
\]

3. Substitute the result back into the expression:
\[
8 - 3 + 5
\]

4. Now, compute \( 8 - 3 \):
\[
8 - 3 = 5
\]

5. Finally, add 5:
\[
5 + 5 = 10
\]

Thus, the evaluated expression \( 2a - 3 + b \) equals \( 10 \).

The answer is **10**.
