Question.  18

q/2 = 3 has a solution

(A)

6

(B)

8

(C)

3

(D)

2

Detailed Answer with Explanation:

Step 1: Understand the equation
We are given: ( dfrac{q}{2} = 3 ). This means “q divided by 2 equals 3.”

Step 2: Remove the division by 2
To undo “divide by 2”, multiply both sides by 2.

Left side: ( 2 imes dfrac{q}{2} = q )

Right side: ( 2 imes 3 = 6 )

So, ( q = 6 ).

Step 3: Check your answer
Put ( q = 6 ) back into the original equation:

( dfrac{6}{2} = 3 ) ✓ True.

Step 4: Match with the options
Options are 6, 8, 3, 2. The correct one is 6.
