\"-%28x%2B1%29+=+2%283x-1%29\"
\n" ); document.write( "\"-x-1+=+2%283x-1%29\" ... distribute the negative sign on the left
\n" ); document.write( "\"-x-1+=+6x-2\" ... distribute the 2 on the right
\n" ); document.write( "\"-1+=+7x-2\" ... add x to both sides
\n" ); document.write( "\"1+=+7x\" ... add 2 to both sides
\n" ); document.write( "\"1%2F7+=+x\" ... divide both sides by 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Thus, x = 1/7. To check, we substitute 1/7 in for x in the original equality, and see if it holds true.\r
