Who is asking: Student
Three whole numbers , when added two at a time,yield the sums 75, 111, and 128.
Find the smallest of these three whole #'s.
If the three numbers are a, b and c where a is the smallest and c is the largest. The sum of the smaller two is 75 and the sum of the larger two is 128. That is
a + c = 111
b + c = 128
