Answer:

The answer is #n=3#

Explanation:

We start from:

#2(n+2)=5n-5#

First step is to multiply expression in brackets by #2#:

#2n+4=5n-5#

Next step is to move variable to left side and numbers to right side:

#2n-5n=-5-4#

Next we simplify the expression by reducing simmilar term on both sides:

#-3n=-9#

Finally after dividing both sides by the factor next to #n# we get the final result:

Answer: #n=3#
