Afla valuarea lui m
300 + m +100 =800. M=
(500- m)+200=600. M=
M-(100+300)=500. M=
600-(m-100)=300. M=

Răspuns :

300+m+100=800
300+m=800-100
300+m=700
m=700-300
m=400

(500-m)+200=600
500-m=600-200
500-m=400
m=500-400
m=100

m-(100+300)=500
m-400=500
m=400+500
m=900

600-(m-100)=300
m-100=600-300
m-100=300
m=300+100
m=400
