You can put this solution on YOUR website!
log2 (x + 4) = 3 + log2 (x - 5)
\n" ); document.write( ":
\n" ); document.write( "Subtract log2 (x-5) from both sides
\n" ); document.write( "log2 (x + 4) - log2 (x - 5) = 3
\n" ); document.write( "same as
\n" ); document.write( "log2(\"%28x%2B4%29%2F%28x-5%29\") = 3
\n" ); document.write( "The exponent equiv
\n" ); document.write( "\"2%5E3\" = \"%28x%2B4%29%2F%28x-5%29\"
\n" ); document.write( "8 = \"%28x%2B4%29%2F%28x-5%29\"
\n" ); document.write( ":
\n" ); document.write( "8(x-5) = x + 4
\n" ); document.write( "8x - 40 = x + 4
\n" ); document.write( "8x - x = 4 + 40
\n" ); document.write( "7x = 44
\n" ); document.write( "x = \"44%2F7\"
\n" ); document.write( "
\n" );
