You can put this solution on YOUR website!
Let $\"+a+\"$ = gallons of 60% sugar solution needed
\n" ); document.write( " $\"+.6a+\"$ = gallons of sugar in 60% solution
\n" ); document.write( "Let $\"+b+\"$ = gallons of water needed
\n" ); document.write( "-----------------------------------------------
\n" ); document.write( "(1) $\"+a+%2B+b+=+6+\"$
\n" ); document.write( "(2) $\"++.6a++%2F+6+=+.5+\"$
\n" ); document.write( "------------------------
\n" ); document.write( "(2) $\"+.6a+=+3+\"$
\n" ); document.write( "(2) $\"+a+=+5+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+a+%2B+b+=+6+\"$
\n" ); document.write( "(1) $\"+5+%2B+b+=+6+\"$
\n" ); document.write( "(1) $\"+b+=+1+\"$
\n" ); document.write( "--------------------
\n" ); document.write( " 5 gallons of 60% sugar solution is needed
\n" ); document.write( "1 gallon of water is needed
\n" ); document.write( "---------------------------
