Tolong bantuin Ya???

Answer 1

1.  |4x-8|=12
     4x-8 = -12  atau 4x-8 = 12
     4x   = -4  atau  4x = 20
     x = -1 atau x = 5
     jadi HP: {-1,5} B
2. |3x-6|=0
    3x - 6 = 0
     3x = 6
      x = 2    (C)
3. |2x/3 + 4 | = 1/7
    2x/3 + 4 = - 1/7      atau 2x/3 + 4 = 1/7
    2x/3 = -29/7          atau  2x/3  = -27/7
    x = -87/14             atau x = - 81/14
    x = -6 3/14            atau x = -5 11/14 
jawaban A

4. |5/ x-1| = 1/2
    5/x-1 = -1/2 atau 5/x-1 = 1/2
    5 . (-2) = x-1 atau 5. (2) = x-1
    -10 + 1 = x atau 10 + 1 = x
    -9 = x atau  11 = x
