Check your equation.
\n" ); document.write( "The real term on the left hand side is $\"m-m\"$ which equals zero.
\n" ); document.write( "I think you meant either $\"m-n\"$ or $\"n-m\"$ .
\n" ); document.write( "From the complex term,
\n" ); document.write( " $\"-4i=ni\"$
\n" ); document.write( " $\"n=-4\"$
\n" ); document.write( "Then either,
\n" ); document.write( " $\"m-n=7\"$ or $\"n-m=7\"$
\n" ); document.write( " $\"m-%28-4%29=7\"$ or $\"-4-m=7\"$
\n" ); document.write( " $\"m%2B4=7\"$ or $\"-m=11\"$
\n" ); document.write( " $\"m=3\"$ or $\"m=-11\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
