bila ada kesalahan mohon dimaafkan. ambil baiknya buang buruknya asslamualaikum

6p + 2q = 12 (×1)
3p + 5q = 15 (×2)

6p + 2q = 12
6p + 10q = 30
------------------------ (-)
-8q = -18
q = 18/8
q = 9/4

q= 9/4 , persamaan (1)
6p + 2q = 12
6p + 2(9/4) = 12
6p + (18/4) = 12
6p + (9/2) = 12
6p = 12 - (9/2)
6p = (24/2) - (9/2)
6p = 15/2
p = (15/2)/6
p = 15/2 × 1/6
p = 15/12
p = 5/4

Hp = { 5/4 , 9/4 }
