#x=3#

Explanation:

Firstly, multiply out the brackets to simplify:

#3x+2(5x+4)=47#
#3x+10x+8=47#

Then rearrange to place all like-terms on one side to simplify:

#13x+8=47#
#13x=47-8#
#13x=39#
#x=39/13#
#x=3#

So when the value of #x# is substituted into the original equation, you should get the solution of #47#:

#3x+2(5x+4)=47#
#3(3)+2(5(3)+4)=47#
#9+2(15+4)=47#
#9+30+8=47#
