<h3>Answer:</h3>

5/2

<h3>Step-by-step explanation:</h3>

Start by eliminating parentheses.

... 2n +4 +6 = -9 +8n +4

... 10 = -5 +6n . . . . subtract 2n

... 15 = 6n . . . . . . . add 5

... 15/6 = n = 5/2

_____

<u>Check</u>

(2·5/2 +4) +6 = -9 +4(2·5/2 +1)

5 +4 +6 = -9 +4(5 +1)

15 = -9 +24 . . . . . true, so the answer checks OK
