To simplify the expression \(2(10b + 4) - (b - 2)\), follow these steps:
1. Distribute the \(2\) in the first term:
\[
2(10b + 4) = 20b + 8
\]
2. Rewrite the expression:
\[
20b + 8 - (b - 2)
\]
3. Distribute the negative sign in the second term:
\[
20b + 8 - b + 2
\]
4. Combine like terms:
\[
(20b - b) + (8 + 2) = 19b + 10
\]
Thus, the simplified expression is:
\[
\boxed{19b + 10}
\]
