Question

What is the value of n in the equation –negative StartFraction one-half EndFraction left-parenthesis 2 n plus 4 right-parenthesis plus 6 equals negative 9 plus 4 left parenthesis 2 n plus 1 right-parenthesis.(2n + 4) + 6 = –9 + 4(2n + 1)?

Answer 1

The value of n is 1

Answer 2

the value of
𝑛
n is 1.

Answer 3

damn

Answer 4

(2n + 4) + 6 = –9 + 4(2n + 1)
Lets subtract 6 from both sides:
2n + 4 = 4(2n + 1) - 15
Distributive property on 4(2n + 1):
2n + 4 = 8n + 4 - 15
Cancel the 4 on both sides (subtract 4):
2n = 8n - 15
Add 15 to both sides:
2n + 15 = 8n
Subtract 2n from both sides:
15 = 6n
Divide both sides by 6:
n = 15/6 which can be simplified to 5/2 or 2.5

Whoever is saying n=1 probably googled it and got it incorrect.

Answer 5

mathness

Answer 6

\[-\frac{ 1 }{ 2}\left( 2n+4 \right)+6=-9+4\left( 2n+1 \right)\]
multiply by 2
-(2n+4)+12=-18+8(2n+1)
-2n-4+12=-18+16n+8
-2n-16n=-18+8+4-12
-18n=-18
\[n=\frac{ -18 }{ -18 }=1\]
n=1

Answer 7

n= 1

Answer 8

it is n=1
