The ages of three sisters are consecutive odd integers. Twice the age
of the youngest sister is one less
than the oldest sisters? Only an algebraic solution will be accepted. Write a let statement too.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The sisters ages are n, n+2, and n+4.
The equation is
2n = (n+4) - 1.
2n = n +3 ---> n = 3.
Answer. 3, 5 and 7 years.
It seems to me that the person who understand the meaning of the words "odd" and "consecutive" must solve it on his/her own
without any difficulties.
