2x+y+3z=-5
2x+2y+2z =6
2x+y+3z =-5
eliminasi jadi y-z = 11 (persamaan 4)
eliminasi persamaan 2&4
3y-z =21
y - z= -11 dikali 3 agar y hilang
3y-z =21
3y-3z =-33
eliminasi jadi 2z =54
z= 27
2x + y + 3z = 5 |×1| 2x + y + 3z = -5 -
y - z = 11
3y - z = 21
y - z = 11 -
2y = 10
y = 10/2
y = 5
y - z = 11
5 - z = 11
-z = 11 - 5
-z = 6
z = -6
