You can put this solution on YOUR website!
(7^x-3)/(7^3x+1)=1

\n" ); document.write( " $\"7%5E%28x-3%29%2F7%5E%283x%2B1%29\"$ = 1
\n" ); document.write( ":
\n" ); document.write( "Just looking at it you have to say:
\n" ); document.write( "3x + 1 = x - 3
\n" ); document.write( "3x - x = -3 - 1
\n" ); document.write( "2x = -4
\n" ); document.write( "x = -2
\n" ); document.write( ":
