Question
Simplify:
a - [2b - {3a - (2b - 3c)}]
a - [2b - {3a - (2b - 3c)}]
✓
Answer
We have:a - [2b - {3a - (2b - 3c)}]
= a - [2b - {3a - 2b + 3c}]
[Removing grouping symbol ( )]
= a - [2b - 3a + 2b - 3c]
(Removing grouping symbol {})
= a - [4b - 3a - 3c]
= a - 4b + 3a + 3c
(Removing grouping symbol [ ])
= 4a - 4b + 3c
= a - [2b - {3a - 2b + 3c}]
[Removing grouping symbol ( )]
= a - [2b - 3a + 2b - 3c]
(Removing grouping symbol {})
= a - [4b - 3a - 3c]
= a - 4b + 3a + 3c
(Removing grouping symbol [ ])
= 4a - 4b + 3c
