Question

A) а + (-3b + 2c) б) -x – (-3p – 2y) в) – (m – 2n) + (3a + b) г) (x – 5) – (7 – x) + (9 – x)

Answer 1

А) а-3b+2c
б) -х+3р+2у
в) -m+2n+3a+b
г) х-5-7+х+9-х=х-3

Answer 2

A)

а + (-3b + 2c)

To simplify this expression, we can first remove the parentheses by distributing the negative sign:

а - 3b + 2c

This is the simplified expression.

B)

-x – (-3p – 2y)

To simplify this expression, we can first remove the parentheses by distributing the negative sign:

-x + 3p + 2y

This is the simplified expression.

C)

– (m – 2n) + (3a + b)

To simplify this expression, we can first remove the parentheses by distributing the negative sign in front of the first set of parentheses, and then combine like terms:

• m + 2n + 3a + b

This is the simplified expression.

D)

(x – 5) – (7 – x) + (9 – x)

To simplify this expression, we can first remove the parentheses by distributing the negative sign in front of the second and third sets of parentheses, and then combine like terms:

x - 5 - 7 + x + 9 - x

Simplifying further by combining like terms:

2x - 3

This is the simplified expression.
