Please look below.

Explanation:

In this question you need to simplify the left hand side so since it is entirely divided by #2# both sides need to be multiplied by #2# to simplify the equation and keep both sides equal.

#(x+4)/2 xx 2 = 7 xx 2#

#x+4 = 14#

Now you can subtract #4# from both sides to find #x#

#x +4 - 4= 14 - 4#

#x = 10#

x=10

Explanation:

We just use simple algebra. I personally like to get rid of the fraction first so this is how I do. #(x+4)/2=7.#
#x+4=7*2#
#x+4=14#
#x=10#
