You can put this solution on YOUR website! let f = Fatima's present age
Let b = Bernice's age
:
Write an equation for each statement
:
Seven years ago Fatima was six times as old as Bernice.
f - 7 = 6(b - 7)
f - 7 = 6b - 42
f = 6b - 42 + 7
f = 6b - 35
:
In one year, she will only be twice as old as Bernice.
f + 1 = 2(b+1)
f + 1 = 2b + 2
f = 2b + 2 - 1
f = 2b + 1
Replace f with (6b-35)
6b - 35 = 2b + 1
6b - 2b = 1 + 35
4b = 36
b = 36/4
b = 9 yrs is B's present age
find f
f =2(9) + 1
f = 19 yrs is F's age

Check this in the statement
"In one year,she will only be twice as old as Bernice."
19 + 1 = 2 (9 + 1)
