What is the value 3+log(base)2 (x) = log(base 2) (x-1)
\n" ); document.write( "log2 (x-1) - log2 (x)=3
\n" ); document.write( "log2[(x-1)/(x)]=3
\n" ); document.write( "convert to exponential form:
\n" ); document.write( "2^3=(x-1)/(x)
\n" ); document.write( "8=(x-1)/(x)
\n" ); document.write( "8x=x-1
\n" ); document.write( "7x=-1
\n" ); document.write( "x=-1/7
\n" ); document.write( "no solution: (x>0) \n" ); document.write( "

\n" );
