n nuts and r raisins;
\n" ); document.write( "\"n%2Br=120\"
\n" ); document.write( "\"n=120-r\"
\n" ); document.write( "-
\n" ); document.write( "Or you can simply use r for how much raisins, and then 120-r is how much nuts. This then is using only a single variable, r.
\n" ); document.write( "-
\n" ); document.write( "Cost must be \"120%2A8\" dollars.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"12n%2B6r=120%2A8\"
\n" ); document.write( "\"12%28120-r%29%2B6r=120%2A8\"
\n" ); document.write( "Quick simplification,
\n" ); document.write( "\"2%28120-r%29%2Br=20%2A8\"
\n" ); document.write( "\"240-2r%2Br=20%2A8\"
\n" ); document.write( "\"240-r=20%2A8\"
\n" ); document.write( "\"r=240-160\"
\n" ); document.write( "\"highlight%28r=80%29\"
\n" ); document.write( "-
\n" ); document.write( "\"highlight%28n=40%29\"\r
