2/5x - 3 = 1

2/5x = 1 + 3

2/5x = 4

x = 4/1 : 2/5

x = 4/1 x 5/2

x = 20/2

x = 10/1

x = 10

Penjelasan dengan langkah-langkah:

2/5 x - 3 = 1

2/5 x = 1 + 3

2/5 x = 4

x = 4 : 2/5

x = 4 x 5/2

x = 10

  • ko bisa 20?
  • bkn ny 10?
  • 2/5x - 3 = 1

    2/5x = 3 + 1
    2/5x = 4
    x = 4 × 5/2
    x = 2 × 5
    x = 10
