#n = 3#

Explanation:

#2n + 1 = 4n - 5#

The first thing we want to do is subtract #2n# from both sides of the equation:
#1 = 2n - 5#

Now we add #5# to both sides of the equation:
#6 = 2n#

Finally, we divide both sides by #2# to get the value of #n#:
#n = 3#

Answer is n=3

Explanation:

Subtract 2n from 2n and 4n, bring down the one an equal sign then solve 4n-2n (write your answer underneath) bring down the 5 which should leave you with "1= 2n - 5". Add five to 1 and 5, the 5 cancels out which leaves you with 1 +5 and that equals 6..divide 6 by 2 and your answer is n=3
