To solve the inequality \( Cx + 4 \leq 18 \), we can follow these steps:
-
Subtract 4 from both sides: \[ Cx \leq 18 - 4 \] \[ Cx \leq 14 \]
-
Now, divide both sides by \( C \) (since \( C > 0 \), the direction of the inequality remains the same): \[ x \leq \frac{14}{C} \]
So the correct answer is:
\( x \leq \frac{14}{C} \)
This corresponds to the response option:
C \(x\) less-than-or-equal-to \( \frac{14}{C} \).
