Question 14563
let's see...we can work this out with an equation

let x represent the age of her son

5x-7=3x-3+6

now....let's solve

5x-7=3x-3+6
5x=3x-3+6+7
5x=3x+16
5x-3x=16
2x=16
x=16/2
x=8

Now that you have the son's age, you can find out mrs. brook's age.

5 x 8-7
40-7
33

Therefore, her son is 8 and she is 33.
