Solve the following equation. Show all your work.
\n" ); document.write( "2log9(2x+5)-1=0
\n" ); document.write( "------
\n" ); document.write( "I'll assume it's log base 9
\n" ); document.write( " $\"2log%289%2C%282x%2B5%29%29-1=0\"$
\n" ); document.write( " $\"2log%289%2C%282x%2B5%29%29+=+1\"$
\n" ); document.write( " $\"log%289%2C%282x%2B5%29%5E2%29+=+1\"$
\n" ); document.write( "Both sides are exponents of 9
\n" ); document.write( " $\"%282x%2B5%29%5E2+=+9\"$
\n" ); document.write( "2x+5 = 3 or -3
\n" ); document.write( "2x = -2 and -8
\n" ); document.write( "x = -1 and -4\r
\n" ); document.write( "

\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
