⇒ 6x + 5y = 227 $ ⇒ x = (227 - 5y) / 6
y 5x + 4y = 188 $ ⇒ x = (188 - 4y) / 5
⇒ igualamos: (227 - 5y) / 6 = (188 - 4y) / 5
resolvemos (227 - 5y) 5 = (188 -4y) 6
1135 - 25y = 1128 - 24y
1135 - 1128 = 25y -24y
7 = y
remplazamos y=7 en las ecuaciones de la primeraparte
x = (227 -5y) / 6
x= 227 -35)/6 ⇒ x= 32
⇒ 1 litro de café vale 32 $
y 1 litro de bebida 7 $
