Question

Which one is the correct answer

Answer 1

B.

Explanation:

• 2x - 31 = - 2x - 31

• 4x = 0
• x = 0

Other equations don't have any value of x.

Answer 2

• 
  `2x-31=-2x-31`

Because if you see.. The component of x will get canceled in each of the other 3 options.. ( 2x - 2x) which means no solution.. In option B.. 2x + 2x will give 4x..= 31-31 = 0..
