First brother's age = x years
Second brother's age = x+10  years
x+10+x  =  11
2x + 10  =  11
2x  =  11-10
2x  =  1
x  =  1/2
First brother's age = 1/2 years =  6 months
Second brother's age = x+10  
                                        =  10 years  +  6 months
                                        =  6 months  +  10 years
