Let $\"+a+\"$ = grams of white four used
\n" ); document.write( "Let $\"+b+\"$ = grams of light rye flour used
\n" ); document.write( "Let $\"+c+\"$ = grams of dark rye flour used
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"+b+=+%283%2F4%29%2Ac+\"$
\n" ); document.write( "(2) $\"+a+=+%281%2F2%29%2Ac+\"$
\n" ); document.write( "(3) $\"+a+%2B+b+%2B+c+=+1000+\"$
\n" ); document.write( "Substitute (1) and (2) into (3)
\n" ); document.write( "(3) $\"+%281%2F2%29%2Ac+%2B+%283%2F4%29%2Ac+%2B+c+=+1000+\"$
\n" ); document.write( "Multiply both sides by $\"4\"$
\n" ); document.write( "(3) $\"+2c+%2B+3c+%2B+4c+=+4000+\"$
