Question

a+b+c=60 a+b=3*c b+c=3*a a=? b=?c=?

Answer 1

A+b+c=60
a+b=3*c
b+c=3*a
3c + c = 60
4*c = 60
c = 60 : 4
c = 15
a + 3a = 60
4a = 60
a = 60 : 4
a = 15
15 + b + 15 = 60
30 + b = 60
b = 60 - 30
b = 30
Acum să verificăm :
15 + 30 = 3 * 15
45 = 45 (corect)
30 + 15 = 3 * 15
45 = 45(corect)
a = 15
b = 30
c = 15

Answer 2

a+b+c=60
a+b=3c
3c+c=60
4c=60
c=15
b+c=3a
a+3a=60
4a=60
a=15
15+15+b=60
30+b=60
b=30
