Eu am inteles din enuntul problemei :
a + b + c = 369
a = [tex] \frac{3}{4} [/tex] · b
b = 2c
a + b + c = 369 / · 2
2a + 2b + 2c = 738
2 · [tex] \frac{3}{4} [/tex] · b + 2b + b = 738
[tex] \frac{6}{4} [/tex] · b + 3b = 738
(Aducem la acelasi numitor inmultind 3b cu 4)
[tex] \frac{6b + 12b}{4} [/tex] = 738
[tex] \frac{18b}{4} [/tex] = 738
18b = 738 · 4
18b = 2952
b = 2952 : 18
b = 164
a = [tex] \frac{3}{4} [/tex] · b
a = [tex] \frac{3}{4} [/tex] · 164
a = [tex] \frac{492}{4} [/tex]
a = 123
2c = b
2c = 164
c = 164 : 2
c = 82
a = 123
b = 164
c = 82
