Define some variables, and write some equations.

OpenStudy (anonymous):

its the first one, 16.

OpenStudy (anonymous):

That's the opposite of helpful, tan.

OpenStudy (anonymous):

just do trial and error for these small ones :P

OpenStudy (anonymous):

say, the age of younger brother is x years now so, age of older brother: 3x/2 now, according to the problem, (x+8)/(3x/2 + 8)=3/4 solve this

OpenStudy (anonymous):

ok just sec

OpenStudy (anonymous):

so ur solving for ex

OpenStudy (anonymous):

Depends on what x is =) That's the "define your variables" part.

OpenStudy (anonymous):

oh ok

OpenStudy (anonymous):

yes, x is the age of the younger brother, as i assumed ^^

OpenStudy (anonymous):

16

OpenStudy (anonymous):
