# Is there one or more solutions to this system of stiff linear equations?

it is a question of hydrodynamics,and i have evaluated all the known Physical quantity，so there are only 6 unknown,

I use the default of the solve function, but it can’t get a solution,

``sol = Solve[{alpha ==  6.9452661266553415` - (2.691307288165229`*^61 -      6.1630057357396486`*^60 I) aa +   0.0005756591988055512` aa + 1.4836217721967435`*^-8 aa,  alpha ==  6.9452661266553415` + (2.690177977346087`*^61 -      6.1604196508706296`*^60 I) aa -   0.0005795167180894829` aa - 1.4847619644675353`*^-8 aa,  alpha ==  6.9452661266553415` - (2.6867957242378484`*^61 -      6.152674401787605`*^60 I) aa +   0.0005914058327383139` aa + 1.488193080699163`*^-8 aa,  aa == (-0.01865295829650781` +     0.0947158131902396` I) (-7.853457866365679`*^61 -     5.3448365305565616`*^60 alpha +     4.105427712466962`*^61 alpha),  aa == -26.813731172513215` (-0.03198613745886671` -     0.0021923914657948863` alpha +     0.0172071159126169` alpha),  aa == -15804.107513690864` (-0.0039269646434191684` -     0.00026757553967274273` alpha +     0.0020626199050551887` alpha)}, {alpha, alpha,  alpha, aa, aa, aa}] ``

hints are as this,

``RowReduce::luc: Result for RowReduce of badly conditioned matrix {{-1.48362*10^-8+0.     I,-0.000575659+0. I,7.39164*10^62+1.07904*10^62 I,0. +0. I,0. +0. I,1. +0. I,-    6.94527+0.

thanks a lot!
