Diketahui sistem persamaan linear sbg berikut X-y+2z=5 2x+4y-3z=-6 3x-2y+z=-3 Tentukan nilai x-y-z!

x _ y + 2z = 5
2x + 4y _ 3z = _6
3x _ 2y + z = _ 3

x _ y + 2z = 5. x 3
2x + 4y _ 3z = _ 6. x 2

3x _ 3y + 6z = 15
4x + 8y _ 6z = _ 12
________________ +
7x + 5y. = 3

2x + 4y _ 3z = _6. x 1
3x _ 2y + z = _ 3. x 3

2x + 4y _ 3z = _ 6
9x _ 6y + 3z = _ 9
_______________ +
11x _ 2y = _ 15

7x + 5y = 3. x 2
11x _ 2y = _ 15. x 5

14x + 10y = 6
55x _ 10y = _ 75
______________ +
69x. = _ 69
x = _69/69
x = _ 1

(14 x _ 1 ) + 10y = 6
10y = 6 + 14
y = 20/10
y = 2

x _ y + 2z = 5
_1 _ 2 + 2z = 5
_3 + 2z = 5
2z = 5 + 3
z = 8/2
z = 4
jadi hp ( x = _1)
( y. = 2)
( z = 4)
