Saved 2490

Žeňa and Ivan saved a total of 800 CZK. How much did Ivan save if he had saved 80 CZK more than Žeňa?

Correct answer:

x =  440 Kc

Step-by-step explanation:


x+y = 800
x =80+ y

x+y = 800
x-y = 80

Row 2 - Row 1 → Row 2
x+y = 800
-2y = -720


y = -720/-2 = 360
x = 800-y = 800-360 = 440

x = 440
y = 360
