Question

solve for a. 3a < 9

Explanation:

Step1: Divide both sides by 3

To isolate \( a \), we divide both sides of the inequality \( 3a < 9 \) by 3. Since 3 is a positive number, the direction of the inequality sign remains the same.

$$ \frac{3a}{3} < \frac{9}{3} $$

Step2: Simplify both sides

Simplifying the left - hand side \(\frac{3a}{3}\) gives \(a\), and simplifying the right - hand side \(\frac{9}{3}\) gives 3.

$$ a < 3 $$

Answer:

\(a < 3\)
