Pertanyaan

tentukan nilai x dari:
x+3= 2
x-5= 3
-x+2 = 2
2x+2= 3
2x-4 = 1

2 Jawaban

  • x+3 = 2
    x = 2 - 3
    x = 1

    x - 5 = 3
    x = 3 + 5
    x = 8

    -x + 2 = 2
    -x = 2 - 2
    -x = 0
    x = 0

    2x + 2 = 3
    2x = 3-2
    2x = 1
    x = 1/2

    2x - 4 = 1
    2x = 1+4
    2x = 5
    x =5/2
  • a.x+3=2
    x=2-3
    x=-1
    b.x-5=3
    x=3+5
    x=8
    c.-x+2=2
    -x=2-2
    x=0
    d.2x+2=3
    2x=3-2
    2x= 1
    x = ½
    e. 2x -4= 1
    2x = 1+4
    2x = 5
    x = 5/2
