Răspuns :

Ctinamaria31
a+b+c=458
a=b+8
c=a+16 adica c=b+8+16

inlocuim in prima
b+8 +b+ b+8+16 = 458
3b=458-8-8-16
3b=426
b=142
a=b+8
a=142+8 = 150
c=a+16
c=150+16 = 166
a+b+c=458
a=b+8
c=a+16⇒c=b+8+16⇒c=b+24
a=?

b+8+b+b+24=458
3b+32=458
3b=458-32
3b=426
b=426:3
b=142
a=142+8
a=150
c=150+16
c=166
