Question

1. 15 < 4x

Explanation:

Step1: Isolate the variable \( x \)

To solve the inequality \( 15 < 4x \), we divide both sides by 4 (since 4 is positive, the direction of the inequality sign remains the same).

$$ \frac{15}{4} < x $$

Step2: Simplify the fraction

\( \frac{15}{4} = 3.75 \), so the inequality becomes \( x > 3.75 \).

Answer:

\( x > \frac{15}{4} \) (or \( x > 3.75 \))
