Gray wolf kept in his tent turtles Žofka and Julka, which together have 200 years. After 50 years will Julka 2 times older than Žofka. How old are the turtles?

Correct answer:

x =  150
y =  50

Step-by-step explanation:


x+y= 200; x+50 =2(y+50)

x+y= 200
x+50 =2•(y+50)

x+y = 200
x-2y = 50

x = 150
y = 50
