What is the value of n in the equation - {(2n + 4) + 6 = -9 +4(2n + 1)

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)
