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 .
