To combine the like terms in the expression \( 2x - 18 - 12x + 30 \), we will group the \( x \) terms and the constant terms separately.
1. Combine the \( x \) terms:
\[
2x - 12x = -10x
\]
2. Combine the constant terms:
\[
-18 + 30 = 12
\]
Putting it all together, we get:
\[
-10x + 12
\]
Therefore, the answer is \( \text{b } -10x + 12 \).
