Answer:

n=13/7

Step-by-step explanation:

2n+4+6*2=-9*2+8(2n+1)

2n+4+12=-18+16n+8

16+18=16n-2n+8

34=14n+8

34-8=14n

26=14n

n=13/7

Answer:

n = 13/7

Step-by-step explanation:

Solve the equation

Step 1:  Use distributive property to multiply out the terms with parenthesis

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

    n + 2 + 6 = 9 + 8n + 4

Step 2: combine like terms...

     n + 8 = 8n - 5

Step 3:  Get all "n's" to one side, and all constants on the other and solve

      13 = 7n      (subtract n from both sides and add 5 to both sides)

     13/7 = n   (divide both side by 7)
