Find a new set of integers.?

Suppose a,b,c are distinct integers. Define a new set of integers, called the "sugmented set of { a,b,c }" by constructing {ab+c, ac+b, bc+a, a(b+c), b(a+c), c(a+b)}. What set {a,b,c} has its augmented set {25,29,79,36,91,99}?

Find a new set of integers.?
ab+bc=91


ab+c=25


therefore bc-c=66


c(b-1)=66


c=11 or 6


b= 12 or 7





If c = 11, then b = 7, and a = 2 (ab+c=25 =%26gt; 7a+11=25)
