1. Answer:

   n = 2.5 or n = (5/2)

   Step-by-step explanation:

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

   first distribute the 4 to the (2n+1)

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

   then add 9 to both sides to cancel out the -9 on the right side

   (2n+4) +15 = (8n+4)

   next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract

   15 = 6n

   then divide 15 by 6 to get your final answer

   n = 2.5

   or

   n = (5/2)
