Question

Given: x - 5 > -2. Choose the solution set. x R, x > -7 x x R, x > 3 x

Answer 1

x ∈ R, x > 3

Explanation:

We are given the following inequality:

x - 5 > -2

In order to find the solution, we have to isolate the x on one side. This can be done by adding 5 to both sides of the inequality as shown below:

x - 5 + 5 > -2 + 5

x > 3

So the solution of the inequality is set of all numbers where x > 3. This is represented by 3rd option.

So, x ∈ R, x > 3 is the answer.
