#x##=##7/12#

Steps:

Step 1: Take out those parentheses by mutiply 3 with the numbers inside the parentheses.

#3##(##4##x#+#5#)#=# #12x+5#

So now, the equation will be, #12x+5##=##12#

Step 2: Now we are going to leave #x# by itself on one side.

#12x+5##=##12#

#12x##=##12##-##5#

#12x##=##7#

Then, after you divide take #12# to the other side, you will have your answer:
#x##=##7/12#

You cannot simplify it, so #7/12# is your final answer!

I hope this helps!
All the best,
