Tentukan Hp dari 1). x-3y+2z =9 2x+4y-3z=-9 3x-2y+5z= 12 Tolong jawab yg jelas dan benar poin nya 10 nihh

x _ 3y + 2z = 9. x 2
2x + 4y _3z = _ 9. x 1

2x _ 6y + 4z = 18
2x + 4y _ 3z = _ 9
________________ _
_ 10y + 7z = 27

2x + 4y _ 3z = _ 9. x 3
3x _ 2y + 5z = 12. x 2

6x + 12y _ 9z = _ 27
6x _ 4y + 10z = 24
__________________ _
16y _ 19z = _ 51

_ 10y + 7z = 27. x 16
16y _ 19z = _51. x 10

_ 160y + 112z = 432
160y _ 190z = _ 510
__________________ +
_78z. = _ 78
z = _ 78/_ 78
z = 1
_ 10y + ( 7 x 1) = 27
_10y = 27 _7 = 20
y = 20/ _ 10
y = _ 2

x _ 3y + 2z = 9
x _ ( 3 x _ 2) + ( 2 x 1) = 9
x = 9 _6 _2 = 1
x = 1
hp ; x = 1
y = _2
z = 1
