Sylva and Šárka have 20 CZK together. If Sylva gives Šárka 6 CZK, they will have the same. Sylva has how many more CZK?

Correct answer:

a =  16
b =  4
x =  12

Step-by-step explanation:


a+b = 20
a-6 = b+6

a+b = 20
a-b = 12

Row 2 - Row 1 → Row 2
a+b = 20
-2b = -8


b = -8/-2 = 4
a = 20-b = 20-4 = 16

a = 16
b = 4

x=ab=164=12
