Okay, this is the solution:
First you multiply the number 2 by everything contained in the bracket as shown below
2(x) + 2(2) =6x
2x + 4 = 6x
Next you group the like terms together that is, the x's by sending 2x to the other side of the = sign
4= 6x - 2x
Now that the like terms are grouped, we can now proceed to any arithmetic left ( -, +,...)
4= 4x
Finally we can find the x value by eliminating the 4 next to it through division as follows
4/4 = 4x/4
When the cancellation is done we will have our answer
x = 1/1
x = 1
