Let \"+a+\" = cost of 1 pound of peanuts in dollars
\n" ); document.write( "Let \"+b+\" = cost of 1 pound of cashews in dollars
\n" ); document.write( "----------------------------------------
\n" ); document.write( "(1) \"+5a+%2B+6b+=+11.2+\"
\n" ); document.write( "(2) \"+3a+%2B+7b+=+10.8+\"
\n" ); document.write( "--------------------------
\n" ); document.write( "(1) \"+50a+%2B+60b+=+112+\"
\n" ); document.write( "(2) \"+30a+%2B+70b+=+108+\"
\n" ); document.write( "--------------------------
\n" ); document.write( "(1) \"+25a+%2B+30b+=+56+\"
\n" ); document.write( "(2) \"+15a+%2B+35b+=+54+\"
\n" ); document.write( "--------------------------
\n" ); document.write( "Multiply both sides of (1) by \"+15+\"
\n" ); document.write( "Multiply both sides of (2) by \"+25+\"
\n" ); document.write( "Subtract (1) from (2)
