2x + 3 > 7
2x + 3 - 3 > 7 - 3
2x > 4
2x/2 > 4/2
x > 2
The solution is all real numbers greater than 2.

Yes - except in extreme cases. It can be the whole of the Real Numbers: eg x2 > -3 It can be a single point eg x2 ≤ 0 gives x = 0
prime numbers
The main difference is that if you multiply both sides of an inequality by a negative number, you have to change the direction of the inequality sign - for example "greater than" would become "less than".
All of them except 31 and 37 which are prime numbers
I don't see any numbers below.One method to solve this is to replace each of the numbers in the inequality, do the calculations, and then check whether the inequality is satisfied. Another method is to get the general solution for the inequality, then check with each of the numbers.

The way you state it, that is already the solution of some problem; perhaps of an inequality. There is nothing more you need to do, except perhaps graph it, if the problem asks for it.The way you state it, that is already the solution of some problem; perhaps of an inequality.

The inequality with the terms 2x, 3 and 7 can be written as 2x -3 = 7, 2x + 3 = 7, 2x * 3 = 7, and 2x/3 = 7. This means that the solutions are 5, 2, 7/4, and 21/2 respectively.

"Prime" numbers
That is the definition of prime numbers.
No. It is about the same amount except there are more numbers after the decimals so 1.32 is greater.

Natural numbers that are greater than zero that have no other factors except one and themselves are called prime numbers. The first five prime numbers are 1, 3, 5, 7, and 11.
