To solve the inequality \( Cx + 4 \leq 18 \):
-
Subtract 4 from both sides: \[ Cx \leq 14 \]
-
Now, divide both sides by \( C \) (since \( C > 0 \), we do not need to reverse the inequality): \[ x \leq \frac{14}{C} \]
Thus, the correct solution to the inequality \( Cx + 4 \leq 18 \) is: \[ x \leq \frac{14}{C} \]
So the correct response from the options provided is:
- x ≤ 14/C.
