To combine the like terms in the expression \(2x - 18 - 12x + 30\), follow these steps:
1. Combine the \(x\) terms:
\[
2x - 12x = -10x
\]
2. Combine the constant terms:
\[
-18 + 30 = 12
\]
Putting it all together, we get:
\[
-10x + 12
\]
Thus, the simplified expression is:
\[
\boxed{-10x + 12}
\]
So the correct answer is **b** \(-10x + 12\).
