I've a simultaneous linear equation with complex numbers i'd like to put through Mathematica (I'm assuming this is possible!) Solve [((2 + 4\[ImaginaryI])*a) + ((1 + \[ImaginaryI])*b) = (118 + 24\[ImaginaryI]), ((1 + \[ImaginaryI])* a) + ((3 + \[ImaginaryI])* b) = {110 + \[ImaginaryI]0}, {a, b}] (all on one line but split for some sort of clarity here) I get this as the output: Set::"write": "Tag \!\(Plus\) in \!\(\(\(\(\((2 + \(\(4\\ \ \[ImaginaryI]\)\))\)\)\\ a\)\) + \(\(\(\((1 + \[ImaginaryI])\)\)\\ b\)\)\) is \ Protected." Set::"write": "Tag \!\(Plus\) in \!\(\(\(\(\((1 + \[ImaginaryI])\)\)\\ a\)\) \ + \(\(\(\((3 + \[ImaginaryI])\)\)\\ b\)\)\) is Protected." General::"ivar": "\!\(110 + \[ImaginaryI]0\) is not a valid variable." Solve[118 + 24 \[ImaginaryI], {110 + \[ImaginaryI]0}, {a, b}] Any ideas as to what i'm doing wrong as the error messages don't make it obvious (at least to me as a 4 day old user!!) Also I seem to HAVE to use the esc ii esc where i would prefer to use lower case J (as an electrical eng) is there something special that needs to be done to use lower case J as in the help files it appears to be in bold --
