\"3x+-+4%282x+%2B+1%29+=+21\"\r
\n" ); document.write( "\n" ); document.write( "The first step here would be to distribute the 4 through the parentheses:\r
\n" ); document.write( "\n" ); document.write( "\"3x+-+4%282x%29+-4%281%29+=+21\"
\n" ); document.write( "\"3x+-+8x+-+4+=+21\"\r
\n" ); document.write( "\n" ); document.write( "Now we combine like terms:\r
\n" ); document.write( "\n" ); document.write( "\"-5x+-+4+=+21\"\r
\n" ); document.write( "\n" ); document.write( "Add 4 to both sides:\r
\n" ); document.write( "\n" ); document.write( "\"-5x+=+25\"\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by -5:\r
\n" ); document.write( "\n" ); document.write( "\"x+=+-5\"
\n" ); document.write( "
