Question

a+d+c=936 a:b=3 c:b=2resr108 a=? b=? c=?

Answer 1

a+b+c=936
a÷b=3 => a=3b
c÷b=2 rest 108 => c=2b+108
3b+b+2b+108=936
6b=936-108
6b=828
b=138
a=3b=3×138=414
c=2b+108=2×138+108=276+108=384

verificare: 138+414+384=552+ 384= 936

coroana?

Answer 2

a+b+c= 936
a:b= 3 ⇒ a=3b
c:b= 2 r 108 ⇒ c= 2b+108
inlocuim in prima relatie
3b + b+ 2b+108= 936
6b= 936- 108
6b=828
b=138
a= 3x138
a=414
c= 2x138+108
c=384
V: a+b+c= 414+138+384= 936 ( adevarat)
