Question

Se dau relatiile: a:b=3 rest 5; c:b=2; a+b+c=59. Ce valori au a, b, c?

Answer 1

a : b = 3 rest 5
a = 3b + 5
c : b = 2
c = 2b
a + b + c = 59
3b + 5 + b + 2b = 59
6b = 59 - 5
b = 54 : 6
b = 9
c = 2 * 9
c = 18
a = 3 * 9 + 5
a = 32

Answer 2

a:b=3 rest 5 rezulta a=3b+5
c:b=2 rezulta c=2b
a+b+c=3b+5+b+2b=59
6b+5=59
6b=59-5
6b=54
b=9 rezulta a=3x9+5=27+5=32
c=2x9=18
