Nehemiah Wang · Answer 2

13/7 = n

Step-by-step explanation:

1/2 (2n+4) + 6=-9+4 (2n+1)

Distribute

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

Combine like terms

n + 8 = 8n - 5

Subtract n from each side

n+8-n = 8n-n-5

8 = 7n-5

Add 5 to each side

8+5 = 7n-5+5

13 = 7n

Divide each side by 7

13/7 = 7n/7

13/7 = n
