Answer 1

Step-by-step explanation:

3xy-5xy-2xy+xy-9xy first we will sub 3xy-5xy=-2xy now, -2xy+{-2xy}=-4xy +xy=-3xy-9xy=-12xy. answer plz increase my points

Answer 2

Answer:

$8xy$

Step-by-step explanation:

As we have given in the question, We need to simplify very basic equation, All we have to do is to open the brackets from the innermost bracket and then solve the equation

Thus the given equation is

$3xy-[5xy-2xy+(xy-9xy)]$

We should start solving it from the innermost bracket and mind the signs i.e. negative and positive

=$3xy-[5xy-2xy-8xy]$

=$3xy-[-5xy]$

Therefore our final answer must be

=$8xy$
