Siblings 18943

Two siblings, Eva and Peter, saved a total of 228 CZK. Eva saved three times more than Peter. How much did each of them save?

Correct answer:

x =  152
y =  76

Step-by-step explanation:


x+y=228
x=2y

x+y=228
x=2·y

x+y = 228
x-2y = 0

Row 2 - Row 1 → Row 2
x+y = 228
-3y = -228


y = -228/-3 = 76
x = 228-y = 228-76 = 152

x = 152
y = 76
