Let the income before taxes = \"x\"
\n" ); document.write( "The income after taxes will then be \"x+-+.1%2A%28x+-+3000%29\"
\n" ); document.write( "The problem says the income after taxes is \"12000\", so
\n" ); document.write( "\"x+-+.1%28x+-+3000%29+=+12000\"
\n" ); document.write( "\"x+-+.1x+%2B+300+=+12000\"
\n" ); document.write( "\".9x+=+12000+-+300\"
\n" ); document.write( "\".9x+=+11700\"
\n" ); document.write( "\"x+=+13000\"
\n" ); document.write( "The income before taxes was $13,000
\n" ); document.write( "
\n" );
