    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
