Sasha jumped 131 cm Peter 4 cm more than Jirka.
Jirka 6 cm less than Misha. Misha 7 cm less than Filip, and Filip is half as much as Sasha and Petr together. How far does each jump?

Correct answer:

S =  131 cm
P =  113 cm
J =  109 cm
M =  115 cm
F =  122 cm

Step-by-step explanation:

S=131=131 cm
P = 4+J  J = M6  M = F  7  F = (S+P)/2  F = (S+P)/2 = (4+J+S)/2 = (4+M6+S)/2 = (4+F76+S)/2 F = (4+F76+S)/2 2F = 4+F76+S F=476+S=476+131=122 cm M=F7=1227=115 cm  J=M6=1156=109 cm  P=4+J=4+109=113 cm
