Question

Suma a trei numere este 35 primul este jumatate din al doilea. Daca il imparti pe al doilea la al treilea obtinem catul 2 si restul 5. Aflati numerele.

Answer 1

a+b+c=35
a=b/2,2a=b,a=2c+5/2
b:c=2rest5
b=2c+5

2c+5/2+(2c+5)+c=35
2c+5+4c+10+2c=70
8c=55
c=55/8=6,875
b=2x6,875+5=13,75+5=18,75
a=18,75:2=9,375

Answer 2

[tex]a+b+c=35\\ a=b/2,2a=>b,a=2c+5/2\\ b:c=2~rest~5\\ b=2c+5\\ 2c+5/2+(2c+5)+c=35\\ 2c+5+4c+10+2c=70\\ 8c=55\\ c=55/8\\ \boxed{c=6,875}\\ b=2*6,875+5\\ b=13,75+5\\ \boxed{b=18,75}\\ a=18,75:2\\ \boxed{a=9,375}[/tex]
