Simplify the following:
7 - 3 (9×2 n + (3 n + 8 n)/(-n))

3 n + 8 n = 11 n:
7 - 3 (9×2 n + (11 n)/(-n))

(11 n)/(-n) = n/n×11/(-1) = 11/(-1):
7 - 3 (9 2 n + 11/(-1))

Multiply numerator and denominator of 11/(-1) by -1:
7 - 3 (9 2 n + -11)

9×2 = 18:
7 - 3 (18 n - 11)

-3 (18 n - 11) = 33 - 54 n:
33 - 54 n + 7

Add like terms. 7 + 33 = 40:
40 - 54 n

Factor 2 out of 40 - 54 n:

Answer: 2 (20 - 27 n)

<h3>What is the definition of inequality?</h3>

Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.

The complete question is;

"Which are correct representations of the inequality 6x ≥ 3 + 4(2x – 1)? Check all that apply.

A)1 ≥ 2x

B)6x ≥ 3 + 8x – 4"

6x ≥ 3 + 4(2x – 1)

6x≥3+8x-4

The correct representations of inequality 6x>3+4(2x-1) will be 6x ≥ 3 + 8x – 4.

Hence, option B is correct
