Tentukan Himpunan penyelesaian B.1/3x - 1/2y =1 1/6 1/2x + 1/4y = -1 1/4

1/3X - 1/2Y =1 1/6 [.2]
1/2X + 1/4Y = -1 1/4 [.4]

2/3X - Y = 22/6
2X + Y = -44/4
------------------------- (+)
8/3X = -176/4
8X = (-176/4) . 3
8X = 132
X = 132/8
X = 16 1/2


1/2X + 1/4Y = -1 1/4
1/2 (132/8) + 1/4Y = -11/4
8 1/4 + 1/4Y = -11/4
1/4Y = -11/4 - 8 1/4
1/4Y = -11
Y = -11 . 4
Y = -44

HP :
X = 16 1/2
Y = -44

itu menurut saya guys, mohon maaf apabila ada kekeliruan
