Given that 3^x=9^x+1 work out the value of x.\r
\n" ); document.write( "\n" ); document.write( "My wrong workings:
\n" ); document.write( "3x=9x+1
\n" ); document.write( "X+1squareroot 3x=9
\n" ); document.write( "X=9-x+1squareroot3x
\n" ); document.write( "
It must be \"3%5Ex+=+9%5E%28x+%2B+1%29\". You need to USE PARENTHESES. Write back and I'll solve in detail if I have the time. 
\n" ); document.write( "In the meanwhile, the solution is: \"highlight_green%28x+=+-+2%29\" because anything else does not make any sense.
\n" ); document.write( "It's simple, as in: 3^x = 9^(x + 1). Understand? \n" ); document.write( "
\n" );
