February 20th, 2023
Age of Sherry‘s dad ##=42years##
Age of sherry ##=17years##
Let age of Sherry be ##y## and her dad be ##x##
So we can write
##x+y=59##
##x-y=25##
Adding up both the equations
We get
##x+y+x-y=59+25##
or
##2x+0=84##
or
##2x=84##
or
##x=84/2##
or
##x=42##
Therefore;Age of Sherry’s dad ##=42years##
Age of sherry ##=42-25=17years##
