Cevap:
a=3k b=7k olur a+b=140 ise 10k=140 tan k=14
a=42 b=98 olur
x=2k y=3k z=4k ve 2x-y+3z=169 ise
4k-3k+12k=169 ise 13k=169 ve k=13 olur
x=26 y=39 z=52
a=3k b=2k ise a+b=105 ten 5k=105 ise k=21
a=63 b=42
x=k/5 y=k/2 ve z=k/3
3x+y-z=69 ise 3k/5+k/2-k/3=69
(18k+15k-10k)/30=69
23k=30*69 ise k=90 olur
x=90/5=18, y=90/2=45, z=90/3=30
