Complex Number Simultaneous Equation 2 Unknowns

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
