Answer 1

  U = Q

  a) x-9=0 ---> x = 9/1
  b) x+8=0---> x = -8/1
  c) x-x/3=0 --> (3x-x)/3 = 2x/3
  d) x+3=0 ---> x = -3/1
  e) x-14=2 --> x =2+14 --> x = 16/1
  f) x-7=-11--> x =-11+7 --> x= -4/1
 g) 2x=-18 --> x = -18/2 --> x= -9/1
 h) 5x=-40 --> x= -40/5 ---> x = -8/1
 i)  3x=-3 ---> x = -3/3 ---> x = -1/1
 j) x/3=5 ----> x = 15/1
k) x-1/3=2/3--> x= 2/3+1/3---> x= 3/3---> x=1/1
l) 4x+1=x+7---. 4x-x=7-1---> 3x=6 --> x= 6/3 --> x=2/1
