a+b+c=246
a=2b
b=c+36 => c=b-36
Inlocuim in prima ecuatie
2b+b+b-36=246 ⇔ 4b= 246+36= 282 ⇒b=282/4=70,5
a= 141 c=34,5
a+b+c=246
a=2b
b=c+36 => c=b-36
Inlocuim in prima ecuatie
2b+b+b-36=246 ⇔ 4b= 246+36= 282 ⇒b=282/4=70,5
a= 141 c=34,5
1. a+b+c=246
b=2a deci a=b/2
b=c-36 deci c=b+36;
inlocuiesti in prima ecuatie si
b/2+b+b+36=246
in final da b=84, a=42 si c=120
b=2a deci a=b/2
b=c-36 deci c=b+36;
inlocuiesti in prima ecuatie si
b/2+b+b+36=246
in final da b=84, a=42 si c=120
