#x =6#

Explanation:

So, first using the distributive property, you distribute the #2# to #(2x+4)#. You get #4x+4#. Next, you add the #-2x# and the #4x# to get #2x#. After you subtract the #4# from the #16# (You have to subtract, not add #4# because you are moving it across the equal sign. This means you have to use the opposite operation to cancel the #4#. Thus, you subtract #4# to both ends). Your final equation should be #2x=12#. Lastly, you divide #2# to both sides, getting #x=6#.
