Question

suma a trei nr naturale e 150 aflati nr stiind ca primul este cu 6 mai mic decat al doilea iar al doilea e de 6 ori mai mare decat al treilea

Answer 1

a+b+c=150
a=b-6
b=6*c      c=b/6
b-6+b+b/6=150
2b+b/6=150+6
12b/6+b/6=156
13b/6=156
b=156*6/13=72
b=72
a=72-6=66
a=66
c=72/6=12
c=12

Answer 2

a+b+c=150
a=6c-6
b=6c
c+6c+6c-6=150
13c=150+6=156
c=156:13=12
a=12x6=72
b=72+6=78
