6.misal : T-shirt = x sweater = y 2x + y = 300.000 -> x1 = 2x + y = 300.000 x + 2y = 360.000 -> x2 = 2x + 4y = 720.000 ------------------------------------------------------------------- - 3y = 420.000 y = 140.000 2x + y = 300.000 2x + 140.000 = 300.000 2x = 160.000 x = 80.000 Jadi harga kaos 80.000 dan harga sweater 140.000

Anggap T-sihrt=T, dan sweater =S dan dalam satuan rb(agar mudah aja) 2T+S= 300 T+2S=300+60;T=360-2S 2(360-2S)+S=300 -4S+S=300-720 3S=420;S=140
berarti S=140.000; dan 2T+140.000=300.000;T=160.000/2=80.000
T-shirt = x
sweater = y
2x + y = 300.000 -> x1 = 2x + y = 300.000
x + 2y = 360.000 -> x2 = 2x + 4y = 720.000
------------------------------------------------------------------- -
3y = 420.000
y = 140.000
2x + y = 300.000
2x + 140.000 = 300.000
2x = 160.000
x = 80.000
Jadi harga kaos 80.000 dan harga sweater 140.000
2T+S= 300
T+2S=300+60;T=360-2S
2(360-2S)+S=300
-4S+S=300-720
3S=420;S=140
berarti S=140.000; dan 2T+140.000=300.000;T=160.000/2=80.000
