Shoes and slippers

Shoes were three times as many as slippers. If shoes were cheaper by 120, it would be twice as expensive as slippers. How much cost shoes and how much slippers?

Correct result:

x =  360 Kc
y =  120 Kc

Solution:


x= 3y
x-120 = 2y

x= 3•y
x-120 = 2•y

x-3y = 0
x-2y = 120

x = 360
y = 120

Our linear equations calculator calculates it.
