You can put this solution on YOUR website!
Account for the materials.
\n" ); document.write( "x+y=3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Account for the cost of the order purchased.
\n" ); document.write( "(88/0.5)x+(213/0.1)y=1505\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Slightly simplified, the system to solve, using x for quantity of L-Ribose and y for L-Gulose, is \"system%28x%2By=3%2C176x%2B2130y=1505%29\".
\n" ); document.write( "The variables for x and y are in units of GRAMS as arranged here; not milligrams; but you could arrange differently if you preferred.
