1) 8(x+2)=20
2) 2+2 (p +3) =12

2 Jawaban

  • 1) 8(x+2)=20
    8x + 16 = 20
    8x = 20 - 16
    8x = 4
    x = 4/8
    x = 1/2

    2) 2+2 (p +3) =12
    2 (p +3) =12-2
    2p + 6 = 10
    2p = 10 - 6
    2p = 4
    p = 4/2
    p = 2
  • 1. 8x+16 = 20
    8x=4
    x=4/8
    x= 1/2
    2. 4p+12=12
    4p=0
    p=4
