You can put this solution on YOUR website!
log(x)=log(3)+log(x-6)
\n" ); document.write( "log(x) = log[3(x-6)]
\n" ); document.write( "x = 3(x-6)
\n" ); document.write( "x = 3x - 18
\n" ); document.write( "2x = 18
\n" ); document.write( "x = 9
\n" ); document.write( "------------------------
\n" ); document.write( "
\n" ); document.write( "log(X)+log(x-5)=log(6)
\n" ); document.write( "log(x(x-5)) = log6
\n" ); document.write( "x(x-6) = 6
\n" ); document.write( "x^2-6x-6 = 0
\n" ); document.write( "x = [6+- sqrt(36 -4*-6)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [6 +- sqrt(60)]/2
\n" ); document.write( "x = [6 +- 2sqrt(15)]/2
\n" ); document.write( "x = [3 +- sqrt(15)]
\n" ); document.write( "Positive solution:
\n" ); document.write( "x = 3 + sqrt(15)
