7 pangkat x+y =343
7 pangkat x-y = 7 pangkat dua (7 nya sma sama dicoret)
7 pangkat x+y = 7 pangkat 3 (7 nya sama sama dicoret)
berarti ..............
x-y = 2
x+y = 3
_______________ -
-2y = -1
y = 1/2
Haha, saya pinter kan :v
-------> x+y = 3
pakai subsitusi
x+y = 3
2+ y + y = 3
2 + 2y = 3
2y = 1
y = 1/2
x+y = 3
x + 1/2 =3
x = 2 1/2
2. -----> x+y = 5-----> x = 5 -y
----> 2x + 3y = 3
pakai substitusi
2x + 3y = 3
2(5-y) + 3y = 3
10 - 2y + 3y = 3
y = -7
x + y = 5
x - 7 = 5
x = 12
