Q. | 6x - 3 | = 21 के लिए x के मानों का समुच्चय है

• A.
  {-3, 4}
• B.
  {-3, -4}
• C.
  {3, -4}
• D.
  {3, 4}

Answer 1

The correct option is A

{-3, 4}
|6x – 3| = 21 $\to$ 6x - 3 = 21 or 6x - 3 = -21
6x = 24 or 6x = -18
So, x is either 4 or -3


|6x – 3| = 21 $\to$ 6x - 3 = 21 or 6x - 3 = -21
6x = 24 या 6x = -18
अतः x = 4 या -3
