Barborka goes to school with backpack that was 2 - times more expensive than a bag slipper. If backpack was 36 euros cheaper it was cost same as bag slipper. How many cost backpack and how many bas slipper?

Result

x =  72 eur
y =  36 eur

Solution:


x = 2 * y
x-36 = y

x-2y = 0
x-y = 36

x = 72
y = 36
