Answer provided by our tutors
let
w = the age of Mr.Walsh
d = the age of his daughter
Mr. Walsh is 4 times as old as his daughter
w = 4d
in 14 years he will be 2 times as old as his daughter
w + 14 = 2(d + 14)
by solving the system of equations
w = 4d
w + 14 = 2(d + 14)
we find
w = 28 years
d = 7 years
