\"+%285x-7y%29+%2B+%2816x+%2B+8y%29+\" since you are adding ... just add the like variables.
\n" ); document.write( "\"+5x+%2B+16x+=+21x+\"
\n" ); document.write( "\"+-7y+%2B+8y+=+1y+\"
\n" ); document.write( "\"+21x+%2B+1y+\"
\n" ); document.write( "Problem 2
\n" ); document.write( "\"+%287n+%2B+2t%29+%2B+%284n+-+3t%29+\" drop the parenthesis
\n" ); document.write( "\"+7n+%2B+2t+%2B+4n+-+3t+\" combine like terms
\n" ); document.write( "\"+11n+-+1t+\"
\n" ); document.write( "now just dropping the parenthesis ONLY works if adding. If subtracting you have to worry about changing the signs of everything AFTER the subtraction
\n" ); document.write( "
\n" );
