Question

Tolong dongg jawaban Nya.. diisi semua ya.. pakai Cara

Poin ny lumayan nih,,, yg bner y ngisinya

Answer 1

No 1
2x - 3y + 2z = 3
x - y - 2z = -1
------------------------ +
3x -4y. = 2

x - y - 2z = -1. x 3
- x + 2y - 3z = -4. x 2

3x - 3y - 6z = -3
-2x + 4y - 6z = - 8
-------------------------- -
5x - 7y. = 5

3x - 4y = 2. x 5
5x - 7y = 5. x 3

15x - 20y = 10
15x - 21y = 15
-------------------- -
1y = - 5
y = - 5/1
y = - 5
3x - ( 4 x - 5) = 2
3x = 2 - 20
x = - 18/3
x = - 6

2x - 3y + 2z = 3
(2 x- 6) - ( 3 x - 5) + 2z = 3
2z = 3 + 12 - 15 = 0
z = 0/2
z = 0
hp
x = - 6
y = - 5
z = 0
