Three distinct real numbers add up to 89.  The difrerenc between the larger two is twice the differentce between the smaller two.  Tet the smaller two sum to 3 more than the largest number.  What are the three numbers?

a+b+c=89,
a-b =2(b-c),
b+c =a + 3, solve for a, b, c
Use substitutions to get:
a =43,  b = 27  and c =19
