Hello there! 
6 - 2x > 2x + 26
Let's start by subtracting 2x from both sides 
6 - 2x - 2x > 2x - 2x + 26 
-4x + 6 > 26 
Then add -6 to both sides 
-4x + 6 - 6 > 26 - 6 
-4x > 20 
Divide both sides by -4 
-4x/-4 > 20/-4 
x < -5 
As you can see, I change the sign. The reason is because whenever you divide both sides by a negative sign, you MUST change the sign. 
The answer is -5

As always, I am glad to be your helper to night!
