Joann is five years older than her sister Teresa, Joann's age is one less than twice Teresa's. Find the ages of both girls.
------------------------
Equations:
j = t + 5
j = 2t - 1
------------------
Substitute and solve for "t":
t+5 = 2t-1
t = 6 (Teresa's age)
------------
Since j= t+5, j=11 (Joann's age)
