Question: Take fsolve numeric answer

fsolve command return equation solutions in { }, for example {x1=5,x2=6} which the x1 and x2 are not numeric variables and can not be to use in the later. How we can use x1 and x2 similar numeric variables, for example after fsolve command we use "printf("%.10f",x1)" or y=sin(x1*x2) commands.
