#x = 1#.

Explanation:

We start with:
#2x + 4 = 6#. We have to leave #x# alone. So:

  1. We pass the #4# form the left, where it is adding (#+ 4#) to the right, where it will be doing the opposite, so, subtracting:
    #2x = 6 - 4#,
    #2x = 2#.
  2. Now, we pass the #2# from the left, where it is multiplying (#2x# is the same as #2*x#) to the right, were it will do the opposite, dividing:
    #x = 2/2#,
    #x = 1#.

Hope it Helps! :D .
