Answer 1

1) 2x = 14
    x = 14:2 = 7
2) -4x = 12 
    x = 12:(-4) = -3
3) -6x = -3
   x = -3:(-6) = 1/2
4) -3/4x = -3/8
   x = -3/8:(-3/4)
   x = -3/8 . (-4/3) = 1/2
5) -2x = -3/8
   x = -3/8 : (-2/1)           (-2 itu sama aja kayak -2/1)
   x = -3/8 . (-1/2)  = 3/16
6) 1/4x = 2/3
    x = 2/3 : 1/4
    x = 2/3 . 4/1 = 8/3
