Question

[2x–{2x–(2x-2y)–y}–x]=???​

Answer 1

Answer:

x-y

Step-by-step explanation:

[2x-{2x-(2x-2y)-y}-x] = [2x-{2x-2x + 2y-y}-x]

                                 = [2x-y-x]

                                 = x-y

Answer 2

Answer:

${2x - (2x - 2x - ( - 2y) - y } - x$

$2x−(2x−2x−(−2y)−y−x$

$2x - (2y - y) - x$

$2x - y - x$

$2x - x - y$

$x - y$

This is the right answer
