Let \"+m+\" = the weight of a mango
\n" ); document.write( "Let \"+p+\" = the weight of a pineapple
\n" ); document.write( "Let \"+a+\" = the weight of an apple
\n" ); document.write( "-----------------------------------
\n" ); document.write( "(1) \"+m+%2B+p+=+1.25+\"
\n" ); document.write( "(2) \"+m+%2B+a+=+1.35+\"
\n" ); document.write( "(3) \"+a+%2B+p+=+1.9+\"
\n" ); document.write( "---------------------
\n" ); document.write( "This is 3 equations and 3 unknowns,
\n" ); document.write( "so it's solvable
\n" ); document.write( "----------------
\n" ); document.write( "Subtract (1) from (2)
\n" ); document.write( "(2) \"+m+%2B+a+=+1.35+\"
\n" ); document.write( "(1) \"+-m+-+p+=+-1.25+\"
\n" ); document.write( "----------------------
\n" ); document.write( "\"+a+-+p+=+.1+\"
\n" ); document.write( "Add this result to (3)
\n" ); document.write( "\"+a+-+p+=+.1+\"
\n" ); document.write( "\"+a+%2B+p+=+1.9+\"
\n" ); document.write( "----------------
\n" ); document.write( "\"+2a+=+2+\"
\n" ); document.write( "\"+a+=+1+\"
\n" ); document.write( "and
\n" ); document.write( "(2) \"+m+%2B+a+=+1.35+\"
\n" ); document.write( "(2) \"+m+%2B+1+=+1.35+\"
\n" ); document.write( "(2) \"+m+=+.35+\"
\n" ); document.write( "and
\n" ); document.write( "(3) \"+a+%2B+p+=+1.9+\"
\n" ); document.write( "(3) \"+1+%2B+p+=+1.9+\"
\n" ); document.write( "(3) \"+p+=+.9+\"
\n" ); document.write( "---------------------
\n" ); document.write( "The weight of a mango is .35 pounds
\n" ); document.write( "The weight of a pineapple is .9 pounds
\n" ); document.write( "The weight of an apple is 1 pound
\n" ); document.write( "---------------------
\n" ); document.write( "check:
\n" ); document.write( "(1) \"+m+%2B+p+=+1.25+\"
\n" ); document.write( "(1) \"+.35+%2B+.9+=+1.25+\"
\n" ); document.write( "(1) \"+1.25+=+1.25+\"
\n" ); document.write( "You can check the other equations\r
