Simplify the following expression.
y + 2x - [{y - (y - x + y )} - (x + y ) + y ] - 2y
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2x.
By using the BODMAS rule:
y + 2x - [ {y - (y - x + y )} - (x + y ) + y ] - 2y
= y + 2x - [ y - y + x - y - x - y + y ] - 2y
= y + 2x - [- y ] - 2y
= y + 2x + y - 2y
= 2x
