the present age of boy is one sixth the age of his father.
5yrs later sum of their ages will be 45 yrs.
find their present ages
:
let f = father's present age
let b = boys present age
:
Write an equation for each statement
;
"the present age of boy is one sixth the age of his father."
b = f
or
f = 6b
:
5yrs later sum of their ages will be 45 yrs.
(f+5) + (b+5) = 45
f + b + 10 = 45
f + b = 45 - 10
f + b = 35
replace f with 6b
6b + b = 35
7b = 35
b = 35/7
b = 5 yrs is the boy
then
6(5) = 30 yrs is father
