You can put this solution on YOUR website!
3^x * 9^2y = 1\r
\n" ); document.write( "\n" ); document.write( "=> 3^(x+4y) = 1, [ because 9 = 3^2]\r
\n" ); document.write( "\n" ); document.write( "so, x+ 4y =0,[ because 3^0 =1 ]\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5 ^(3x+2y) = 5^(-3)\r
\n" ); document.write( "\n" ); document.write( "so, 3x+2y= -3\r
\n" ); document.write( "\n" ); document.write( "now, multiply the second equation by 2 and subtract from first equation, \r
\n" ); document.write( "\n" ); document.write( "x -6x = 0 - (-6)\r
\n" ); document.write( "\n" ); document.write( "=> -5x = 6 \r
\n" ); document.write( "\n" ); document.write( "so, x = -6/5 \r
\n" ); document.write( "\n" ); document.write( "and y = 6/20 \r
