Kryger [21]

Answer:

2(n+3)-6

n=0

Step-by-step explanation:

2(3+n)-6=

Simplifying

2(3 + n) + -6 = 0

(3 * 2 + n * 2) + -6 = 0

(6 + 2n) + -6 = 0

Reorder the terms:

6 + -6 + 2n = 0

Combine like terms: 6 + -6 = 0

0 + 2n = 0

2n = 0

Solving

2n = 0

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Divide each side by '2'.

n = 0

Simplifying

n = 0

How do I solve this inequality?
djverab [1.8K]

Step-by-step explanation:

9 ≤ |4x + 7|

9 ≤ 4x + 7

9 - 7 ≤ 4x

2 ≤ 4x

2/4 ≤ x

<h2>1/2 ≤ x</h2>

9 ≤ |4x + 7|

9 ≤ -(4x + 7)

9 ≤ -4x - 7

9 + 7 ≤ -4x

16 ≤ - 4x

16/-4 ≤ x

<h2>-4 ≤ x </h2>

<h2>{-4 ≤ x ≤ 1/2} </h2>
