A jar contains 24 marbles, some are green and others are blue. If a marble is drawn at random from the jar, the probability that it is green is `2/3`. Find the number of blue balls in the jar.

Explanation

To solve the problem step by step, we can follow these instructions:

### Step 1: Understand the Problem
We know that there are a total of 24 marbles in the jar, which consist of green and blue marbles. The probability of drawing a green marble is given as \( \frac{2}{3} \).

### Step 2: Define Variables
Let \( X \) be the number of green marbles in the jar. Since the total number of marbles is 24, the number of blue marbles can be expressed as:
\[
