You can put this solution on YOUR website!
start with:
\n" ); document.write( "y = (5x)/(8x+7)
\n" ); document.write( "switch the x and y:
\n" ); document.write( "x = (5y)/(8y+7)
\n" ); document.write( "solve for y:
\n" ); document.write( "x = (5y)/(8y+7)
\n" ); document.write( "x(8y+7) = (5y)
\n" ); document.write( "8xy+7x = 5y
\n" ); document.write( "7x = 5y-8xy
\n" ); document.write( "7x = y(5-8x)
\n" ); document.write( "7x/(5-8x) = y
\n" ); document.write( ".
\n" ); document.write( "So, the inverse is:
\n" ); document.write( "7x/(5-8x)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
