You can put this solution on YOUR website!
Write your equation with the necessary care. c=ad/a+12 would be the same as the rendered form, $\"c=ad%2Fa%2B12\"$ which simplifies to $\"c=d%2B12\"$ and this is not what you really have.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your equation must use correctly placed grouping symbols: c=ad/(a+12) which will properly show as $\"c=ad%2F%28a%2B12%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The question requires solving the equation, or formula, for a in terms of c. \n" ); document.write( "
