1.	Simplify the algebraic expressions by removing grouping symbols.5a – (3b – 2a + 4c)
Answer» Given 3x – (y – 2x) Since the ‘–’ sign precedes the parentheses, we have to change the sign of each term in the parentheses when we remove them. Therefore, we have = 3x – y + 2x On simplifying, we get = 5x – y

Answer»

Given 3x – (y – 2x)

Since the ‘–’ sign precedes the parentheses, we have to change the sign of each term in the parentheses when we remove them. Therefore, we have

= 3x – y + 2x

On simplifying, we get

= 5x – y
