-1/2(2n + 4) + 6 = –9 + 4(2n + 1)

1/3=n

Step-by-step explanation:

-1/2(2n + 4) + 6 = –9 + 4(2n + 1)

Distribute:

-1n-2+6=-9+8n+4

Combine like terms:

-1n-2+6=-9+8n+4

-1n+4=-5+8n

Add 1n on both sides:

-1n+4=-5+8n

-1n+1n+4=-5+8n+1n

4=-5+9n

Add 5 on both sides:

4+5=-5+5+9n

9=9n

Divide 9 on both sides:

9/9=9n/9

1=n
