Ireally need explain this to me i keep getting the wrong answer

n = -4

Step-by-step explanation:

First distribute.

2 + 8n = 6n + 6 + 3n

Then combine like terms.

2 + 8n = 9n + 6

Then move the 2 to the other side.

2 - 2 + 8n = 9n + 6 - 2

Then subtract.

8n = 9n + 4

Then move the 9n to the other side.

8n - 9n = 9n - 9n + 4

Then subtract.

-n = 4

Then make n positive by multiplying by -1.

n = -4

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
