Let's simplify the expression step by step:
1. First, distribute the 2 in the first term:
\[
2(10b + 4) = 20b + 8
\]
2. Next, we can rewrite the second term, remembering to distribute the negative sign:
\[
-(b - 2) = -b + 2
\]
3. Now, we can combine both results:
\[
20b + 8 - b + 2
\]
4. Combine like terms:
- Combine the \(b\) terms: \(20b - b = 19b\)
- Combine the constant terms: \(8 + 2 = 10\)
5. Therefore, the simplified expression is:
\[
19b + 10
\]
So, \(2(10b + 4) - (b - 2) = 19b + 10\).
