B Correct answer
Explanation

The given equation is 3(2x + 1) = 7. According to the distributive property of multiplication, 3 × 2x + 3 × 1 = 76x + 3 = 7 Transposing 3 to R.H.S, we get: 6x = 7 – 36x = 4 Dividing both sides of the equation by 6, we get: x = 4/6 = 2/3 The required value of x is 2/3. Thus, the required value of (4x – 3) is -1/3. This answer is correct.
