#x = 0.6 or 6/10#

Explanation:

The first thing you should do is expand the brackets:

#2(x - 4) + 2x = 2x - 8 + 2x#

Then, collect like terms:

#2x - 8 + 2x = -6x - 2# can be simplified to #-8 + 4x = -6x - 2#

You can then simplify the equation even more by subtracting the values from either side of it. Just remember that when you do something to one side, you must do the same thing on the other side of the equals sign:

#-8 + 4x = -6x - 2#

Add 8 to both sides:
#4x = -6x + 6#

Then, add #6x# to both sides:
#10x = 6#

We can then solve for the value of #x# by dividing both sides by 10.

#x = 0.6 or 6/10#
