x + 2y = 5 | kali 1 |
6x - 2y = 16
x + 2y = 5
_____________+
7x = 21
x = 21/7
x = 3
------------------------------------------------------------------------------------------------------------------
x + 2y = 5
3 + 2y = 5
2y = 5 -3
2y = 2
y = 2/2
y = 1
Jadi Hmpunan pnyelesaian nya = (3,1)
**Jadikan jawaban ini sebagai yang terbaik**
x+2y=5
6x-2y=16
x+2y=5
6x+x=16+5
7x=21
x=21/7
x=3
