Let the numbers be a,b,c By the problem, a+b+c=6----------(1) 3c+b=11----------(2) a+c=2b------------(3) Substituting (3) in (1), 2b+b=6 3b=6 b=2-------(4) From (3) b=(a+c)/2-------(5) substituting (5) in (2), 3c+(a+c)/2=11 (6c+a+c)/2=11 (7c+a)/2=11 7c+a=22----------(6) Substituting (4) in (3), a+c=2(2) a+c=4 a=4-c--------(7) Substituting (7) in (6), 7c+4-c=22 6c+4=22 6c=18 c=3--------(8) Substituting (8),(4) in (1), a+2+3=6 a+5=6 a=6-5 a=1. Therefore the three numbers are 1,2,3.
