Simplify the algebraic expressions by removing grouping symbols.a –

1.	Simplify the algebraic expressions by removing grouping symbols.a – [2b – {3a – (2b – 3c)}]
Answer» Given a – [2b – {3a – (2b – 3c)}] First we have to remove the parentheses, then the braces, and then the square brackets. Then we get, = a – [2b – {3a – (2b – 3c)}] = a – [2b – {3a – 2b + 3c}] = a – [2b – 3a + 2b – 3c] = a – [4b – 3a – 3c] On simplifying we get, = a – 4b + 3a + 3c = 4a – 4b + 3c

Answer»

Given a – [2b – {3a – (2b – 3c)}]

First we have to remove the parentheses, then the braces, and then the square brackets.

Then we get,

= a – [2b – {3a – (2b – 3c)}]

= a – [2b – {3a – 2b + 3c}]

= a – [2b – 3a + 2b – 3c]

= a – [4b – 3a – 3c]

On simplifying we get,

= a – 4b + 3a + 3c

= 4a – 4b + 3c
