Answer 1

Hello dear !!

_______________________________

We need to simplify ,

-x + [ 5y - { x - (5y - 2x ) } ]

First , we need to know the proper usage of different kinds of brackets to solve this question .

» 1st Bracket - Denoted as '( )' => We need to solve this first .

» 2nd Bracket - Denoted as ' { } ' => We need to solve this after the completion of 1st bracket .

» 3rd Bracket - Denoted as ' [ ] ' => We need to solve this after the work of 2nd Bracket is completed .

Now , going on to the solution using these methods :

- x + [ 5y - { x - ( 5y - 2x ) } ]

= - x + [ 5y - { x - 5y + 2x } ]

= - x + [ 5y - 3x + 5y ]

= - x + 10 y - 3x

= - 4x + 10 y

Hence , this is your required solution .
