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.
