Jawab:

1. x = 4y

  2 (4y) + 5y = 39

  8y + 5y = 39

  13y = 39

   y = 39/13 = 3

 

   2x + 5 · 3 = 39

   2x + 15 = 39

   2x = 39 – 15

   2x = 24

   x = 24/2 = 12

2. y = 3x

  x + 4y = 26

  x + 4(3x) = 26

  x + 12x = 26

  13x = 26

 x = 26/13 = 2

  2 + 4y = 26

  4y = 26 – 2

  4y = 24

   y = 6
