Pertanyaan

1. 5x=0
2. -1/4x=-1
3. -4/5x=8
4. x/4=5
5. -3x=1

2 Jawaban

  • 1.
    5x = 0
    5x ÷ 5 = 0 ÷ 5
    x = 0

    2.
    - ¼x = - 1
    ¼x = 1
    x = 4

    3.
    - 4/5x = 8
    4/5x = - 8
    4/5x ÷ 4/5 = - 8 ÷ 4/5
    x = - 10

    4.
    x/4 = 5
    4(x/4 = 5)
    x = 20

    5.
    - 3x = 1
    3x = - 1
    x = - ⅓

    Maaf Kalau Salah
  • 1. 5x = 0
    x = 0
    5x : 5 = 0 : 5
    x = 0 : 5

    2. -1/4x = -1
