Tentukanlah himpunan penyelesain dari x-3y=1 danx-2y=2

PLDV.

x-3y = 1.
x-2y = 2.
------------- --.
-y = -1.
y = 1.

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

jd himp. penyelesaiannya adl. {-2,1}.

cmiiw.

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

Hp = {4 , 2}
