You could write it like this.
Solve
Multiply both sides by 7
x > 800 * 7
x > 5600 That would make the inequality equal to 800 if x = 5600.
You need to go just 1 step further. Try 5607. When you divide that by 7, you get 5607/7 = 801 which is 1 bigger than 800.
5607 <<<<< Answer
B) -7 because the dominator must be different by 0.
2(x + 7) ≠ 0 |divide both sides by 2
x + 7 ≠ 0 |subtract 7 from both sides
x ≠ -7
