Question

3×-[5y-{6y+2(10y-x)}]​

Answer 1

Answer:

x + 21y

Step-by-step explanation:

We will follow the rules of bracket removal of mathematics to arrive at our answer.

Always remember to follow the following sequence of brackets to solve first,

1. $\bar{~~~~~~~~}$

2. ( )

3. { }

4. [ ]

Let begin with the solution.

3x - [ 5y - { 6y + 2 ( 10y - x ) } ]

= 3x - [ 5y - { 6y + 20y - 2x } ]

= 3x - [ 5y - { 26y - 2x } ]

= 3x - [ 5y - 26y + 2x ]

= 3x - [ - 21y + 2x ]

= 3x + 21y - 2x

= x + 21y

Answer 2

Answer : x + 21y

Step-by-step explanation:

3x - ( 5y-(6y+2(10y -x) ) )

3x - ( 5y-(6y+20y -2x) )

3x - ( 5y-(26y -2x ) )

3x - ( 5y-26y +2x )

3x - ( 2x -21y)

3x - 2x +21y

x + 21y
