Question

b:a=3rest 4 
c:b=2r 5
c-b=27
RASPUNS DETALIAT!

Answer 1

b = 3a + 4
c = 2b + 5
c = b + 27
( scadem a doua si a treia relatie )
b = 11
c = 38
a = 112

Answer 2

$b:a=3\ \ \ rest\ \ \ 4=>b=3a+4 \\ \\ c:b=2\ \ \ rest\ \ \ 5=>c=2b+5 \\ \\ c-b=27 \\ \\ \\ 2b+5-b=27 \\ \\ 2b-b=27-5 \\ \\ \boxed{b=22} \\ \\ c=2*22+5 \\ \\ \boxed{c=49} \\ \\ \\ 3a+4=b \\ \\ 3a+4=22 \\ \\ 3a=18 \\ \\ \boxed{a=6}$
