Tolong bantu y.... Buat bsk soalnya

2 Jawaban

  • 3.) -4x = 12
    x = 12 / 4
    x = 3

    4.) 5p - 8 = 7p + 2
    5p - 7p = 2 + 8
    -2p = 10
    p = 10 ÷ 2
    p = 5

    5.) 4(x - 3) - 2(x + 4) = 8
    (4x - 12) - (2x + 8) = 8
    (4x - 2x) - (-12 + 8) = 8
    2x + 4 = 8
    2x = 8 - 4
    2x = 4
    x = 4 ÷ 2
    x = 2
  • 3.) -4x=12
    x=12 ÷ (-4)
    x=-3

    4.)5p -8 = 7p +2
    5p-7p=2+8
    -2p = 10
    P= 10 ÷ (-2)
    p= -5

    5.)4x-12-2x-8= 8
    (4x -2x)(-12-8)=8
    2x -20 = 8
    2x = 8+20
    2x = 28
    x= 28÷2
    x= 14

    Semoga membantu
