Answer:
Option A and D are only true.
Explanation:
The equation is given as 2 (4x + 1) -3 = ax + b
⇒ 8x - 1 = ax + b ....... (1)
A. If a = 8 and b = 1, then the equation will have no solution.
D. If a = 2 and b = - 1, then the equation (1) will have exactly one solution.
All the remaining conditions and statements are false.
Therefore, options A and D are only true. (Answer)
