Let the current age of the girl be x. Then the current age of her younger bro will b x5. The current age of her older bro will b x+3 After 2 years girl's age will be x+2 The age of her younger bro after 2 years will b x5+2=x3 The age of her older bro after 2 years will b x+3+2=x+5 (x3)(x+5)=12(x+2) x^2+2x15=12x+24 x^210x39=0 (x13)(x+3)=0 x=13/x=3 Since age cannot b negativ x=13. The current age of her older bro will b 16.
