3x - 2y = 5
------------------ -
3y = 6
y = 2
3x + 2 = 11
3x = 11-2
3x = 9
x = 3
y = 2 dan x = 3
Semoga membantu...
3x - 2y = 5 | x1 -> 3x - 2y = 5
------------------------------------------ --
3y = 6
y = 6/3 = 2
3x + y = 11
3x + 2 = 11
3x = 11 - 2
x = 9/3
x = 3
3x - 2y = 5
3(3) - 2(2) = 5
9 - 4 = 5
jadi HP {x,y} = {3,2}
