2x + y = 8
y = x + 2 / 3
2x + y = 8 Menggunakan eliminasi
- x/3 + y = 2/3
------------------ -
7/3x ( 3/7 ) = 22 / 3( 3/7 )
x = 22 / 7
2(22/7) + y = 8
44/7 + y = 8
y = 8 - 44/7
y = 12 / 7
Jadi himpunan penyelesaiannya = ( 22 / 7, 12 / 7 )
check = 2(22/7) + 12 / 7 = 8
44/7 + 12 / 7 = 8
56/7 = 8
8 = 8 Benar
