Answer provided by our tutors
let
a = Almira's present age
p = Portia's present age
Almira's present age is one more than twice the present age of Portia
a = 1 + 2p
if Portia turns 18, Almira's age will be one less than thrice Portia's present age
a + (18 - p) = 3*p - 1
by solving the system of equations
a = 1 + 2p
a + (18 - p) = 3*p - 1
we find
a = 21 years
p = 10 years
