I need some Math help for Pre-Algebra

What is the solution set to for the given inequality if the replacement set for "x" is {2, 3, 4, 5, 6}

1. 2x + 4 > x + 2

A : x = {2, 3, 4}
B: x = {5, 6}
C: x = {2}
D: x = {2, 3, 4, 5, 6}
--------------------------------------…
2. What is the solution to the open sentence?
3x + 7 = 5x – 1

A: 1
B: 2
C: 3
D: 4
--------------------------------------…
3. Name a related equation.
5x = 20
A: x = 5/20
B: 20 = 5/x

Hey guys I really need help with my math homework. I have been really busy and My teacher won't give me any extra time so I could really use you help thanks
--------------------------------------…

1- 2x+4>x+2
isolate x:
2x-x > 2-4
x>-2
the solution is any numer greater than -2...
in the set {2, 3, 4, 5, 6} all the number are greater than -2
so the whole set... Answer D

2-
3x + 7 = 5x -1
isolate x:
5x - 3x = 7 + 1
2x = 8
x=4
Answer D

3-
5x = 20
devide by 5 on both sides
x= 20/5 Answer C

1). 2x + 4 > x + 2
= 2x - x > 2 - 4
= x > - 2
That means IF x is greater than -2, then this statement will be true.
As all 2, 3, 4, 5,and 6 are greater than -2, then The answer should be :-
Answer = D : { 2, 3, 4, 5, and 6 }

2). 3x + 7 = 5x - 1
= 3x - 5x = -1 -7
= -2x = -8
= x = -8 /-2
= x = 4
Answer : D : 4

3). 5x = 20
= x = 20 / 5 = 4
Answer : D : x = 20 / 5

Qu 1
x = > - 2_____which is not one of the options?

Qu 2
8 = 2x
x = 4_____Option D

Qu 3
x = 20/5____Option D
