Hello there!
22x + 4 = 6 (x +1)
We need to distribute the right part 
22x + 4 = (6)(x)+(6)(1)
22x + 4 = 6x + 6 
Now put all the common terms together. Keep in mind that you need to change the sign as you're doing that. 
22x - 6x = 6 - 4 
16x = 2 
x = 2/16 
x = 1/8  or in decimal x = 0.125 
I hope this answer helps!
