Answer 1

Just do:
2(x+1) + 4 = 8
2(x+1) = 8 - 4
2(x+1) = 4
divide by 2
x+1=2
x=1

Answer 2

You can think it out even without algebra.

If <something> + 4 is 8, <something> must equal 4, right?
If 2<something else> = 4, <something else> must equal 2, right?
If <yet another something> + 1 is 2, <yet another something> must be 1, right?
