Verified Answer :

  1. (hard to type out and cant see photo) 42.72=Answer
     3(5x - 14)=18
    3(5x)=25x
    3(-14)= -42
     25x - 42 = 18
     25x divided by 25= x 
    -42+42=0
    18 divided by 25=.72
    .72+42=42.72
  1. B and C

    2. B
    12x+15 = 12x - 15
    12x + 15 - 12x = 12 - 15 -12x
    15 = -15 which is not true
    So option B.

    3. C
    -5x - 25 = 5x + 25
    -5x - 5x = 25 + 25
    -10x = 50
    x = -5
    It has single solution
    So answer is C.


    Hope it helps!
