Simplify the algebraic expressions by removing grouping symbols.5 + [x

1.	Simplify the algebraic expressions by removing grouping symbols.5 + [x – {2y – (6x + y – 4) + 2x} – {x – (y – 2)}]
Answer» Given 5 + [x – {2y – (6x + y – 4) + 2x} – {x – (y – 2)}] First we have to remove the parentheses, then remove braces, and then the square brackets. Then we get, = 5 + [x – {2y – (6x + y – 4) + 2x} – {x – (y – 2)}] = 5 + [x – {2y – 6x – y + 4 + 2x} – {x – y + 2}] = 5 + [x – {y – 4x + 4} – {x – y + 2}] = 5 + [x – y + 4x – 4 – x + y – 2] = 5 + [4x – 6] = 5 + 4x – 6 = 4x – 1

Given 5 + [x – {2y – (6x + y – 4) + 2x} – {x – (y – 2)}]

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

Then we get,

= 5 + [x – {2y – (6x + y – 4) + 2x} – {x – (y – 2)}]

= 5 + [x – {2y – 6x – y + 4 + 2x} – {x – y + 2}]

= 5 + [x – {y – 4x + 4} – {x – y + 2}]

= 5 + [x – y + 4x – 4 – x + y – 2]

= 5 + [4x – 6]

= 5 + 4x – 6

= 4x – 1
