Step-by-step explanation:

simply write it as :

x-y-2x+y = -2-3

so, here we can see -y and +y are cancel out

-x = -5

Hope you would like this method :)

Answer:

+ - = -

- + = -

+ + = +

- - = - (but we will add the terms)

you just have to learn the rules of polynomials.

it's easy.

+ X - y = - 2xy ( + - = - )

-2x + y = -3xy ( + - = -)

nothing is impossible.This math is made by a human and u are a human.U can definitely learn it.
