Bottle with cork cost 8.8 Eur. The bottle is 0.8 euros more expensive than cork. How much are a bottle and the cork?

Correct answer:

bottle:  4.8 Eur
cork:  4 Eur

Step-by-step explanation:

x+y=8.8 x=y+0.8  x=4.8 Eur
y=4 Eur

x+y=8.8
x=y+0.8

x+y = 8.8
x-y = 0.8

Row 2 - Row 1 → Row 2
x+y = 8.8
-2y = -8


y = -8/-2 = 4
x = 8.8-y = 8.8-4 = 4.8

x = 24/5 = 4.8
y = 4
