2x+3y=1 dan x-y=-2 juga penyelesaianya

eliminasi y
2x + 3y = 1 |x1| 2x + 3y = 1
x - y = - 2 | x3| 3x - 3y = -6
___________ +
5x = -5
x = -5/5
x. = -1

x = -1 disubtutusikan ke pers.
2x + 3y = 1
2(-1) + 3y = 1
-2 + 3y = 1
3y = 1 + 2
3y = 3
y = 3/3
y = 1

jadi HP {(-1,1)}

2x + 3y = 1 + x - y = -2
2x - x + 3y - y + 1 + 2
x + 2y + 3

Maaf kalau salah
