Tentukan himpunan penyelesaian SPLTV berikut 2x + 3y + z = 11 x + 4y + 2z = 14 3x + 5y - z = 7

2x+3y+z = 11
3x+5y-z = 7
------------ +
5x+8y = 18

2x+3y+z = 11 x2
x+4y+2z = 14

4x+6y+2z = 22
x+4y+2z = 14
------------ -
3x+2y = 8

5x+8y = 18
3x+2y = 8 x4

5x+8y = 18
12x+8y = 32
---------- -
-7x = -14
x = -14 : -7
= 2

5x+8y =18
5.2+8y =18
10+8y = 18
8y = 18-10
8y = 8
y. = 1
