    1. 2x + y = 1 (1)
      x + y = 2 (2)

      Step 1 :
      y = 2- x (3)

      Step 2 :
      Masukkan persamaan (3) dalam persamaan (1)
      2x + (2-x) = 1
      x + 2 = 1
      x = -1 (4)

      Step 3:
      Masukkan persamaan (4) dalam persamaan (3)
      y = 2 - (-1)
      = 3

    1. 2x + y = 1(1)
      x + y = 2(2)

      2x + 2y = 4(2)
      2x + y = 1

      2y + Y = 8 + 1
      3y = 9
      y = 9/3
      y = 3

      x + y = 2(2)
      x + 3 = 4
      x = 4-3
      x = 1

      y = 3, x = 1

  3. bagaimana nak selesaikan

    -18-(-15)+x=0

  4. -18 + 15 + x = 0
    -3 + x = 0
    x = 0 + 3
    x = 3
