    3– 32, then values of x are:
    A 1 and 2 Correct Answer Incorrect Answer
    B -1 and 3 Correct Answer Incorrect Answer
    C 2 and 3 Correct Answer Incorrect Answer
    D -1 and 2 Correct Answer Incorrect Answer

    Solution

    32x + 1 – 3x = 3x + 3 – 32 ⇒ 3.32x - 3x - 27.3x + 9 = 0 ⇒ 3.3x(3x - 9) - 1 (3x - 9) =0 ⇒ (3x - 9)(3.3x - 1) = 0 ⇒ 3x = 9 or 3x = 32 So, x = 2 ⇒ 3.3x = 1 ⇒ 3x = 1/3 or 3-1 x = -1
