Question 93856
Question:

combining like terms?

  -(2x+y) - 2(-x-y)


Answer:

First remove the parenthesis  as follows...



-(2x+y) - 2(-x-y)



==> -2x - y + 2x + 2y


Now collect the like terms....



==> -2x + 2x - y + 2y



==> 0 + y = y, which is the simplified answer after collecting like terms.




Hope you found the explanation useful.
