X-10X = 81\r
\n" ); document.write( "\n" ); document.write( "Since there are two X terms that are the same, just do X minus 10X (which is the same as 1 minus 10) and you get -9X.\r
\n" ); document.write( "\n" ); document.write( "So, -9X = 81\r
\n" ); document.write( "\n" ); document.write( "Divide -9 on both sides and you get:\r
\n" ); document.write( "\n" ); document.write( "X= -9
\n" ); document.write( "
