Anna              b+3
Beverly            b
Chuck              b-8
SUM                55


First find Beverly's age b, and evaluate the other two ages.
%28b%2B3%29%2Bb%2B%28b-8%29=55

Anna is 3 years older than her sister, Beverly. Anna's brother, Chuck, is 8 years younger than Beverly. Together the sum is 55.
b) Solve the equation for n (Anna's age)

c) What are their ages?
Anna's age, as suggested is N

Beverly's: N + 3

Chuck's: N + 3 - 8, or N - 5

Their ages sun to 55, so we get: N + N + 3 + N - 5 = 55

Solve for N, Anna's age, as requested, and then find the others' ages.
