Question

Simplify the following algebraic expressions by removing grouping symbols:
a - [2b - {3a - (2b - 3c)}]

✓

Answer

First we have to remove the small brackets, or parentheses, (), then the curly brackets, {}, and then the square brackets, [].
Therefore, we have
a - [2b - {3a - (2b - 3c)}]
= a - [2b - {3a - 2b + 3c}]
= a - [2b - 3a + 2b - 3c]
= a - [4b - 3a - 3c]
= a - 4b + 3a + 3c
= 4a - 4b + 3c
