Peter decided to measure shoes size of his three friends. Measured accurately and wrote as follows:

Venda and Jenda together 52 cm
Jenda and Zdenda together 58 cm
Zdenda and Venda together 54 cm
a) How long measures Vendy, Jenda and Zdenda shoes together?
b) Determine the length of each shoe individually


s =  82 cm
v =  24 cm
j =  28 cm
z =  30 cm


j+z = 58
z+v = 54

j-s+v+z = 0
j+v = 52
j+z = 58
v+z = 54

j = 28
s = 82
v = 24
z = 30
