tentukan penyelesaian dari 4x+5y=17 dan 2x+3y=11

2x+3y=11
—————— *2
4x + 6y = 22
4x + 5y = 17
——————— —
y = 5

4x + 5y = 17
4x = 17 - 25
y = -8/4 = -2

Hp = (x,y) = (5,-2)

2x+3y=11
--> 4x +6y = 22

4x+6y=22
4x+ 5y=17
________ -
y=5

2x+3y=11
2x+ 3(5)=11
2x+ 15 = 11
2x= -4
x= -2

X=-2, Y= 5
(x,y)= (-2,5)
