This inequality is already solved for x.

We can write it in interval notation as: (-2, +oo)

see the solution below

Explanation:

x > -2

since x can take up all values from -2

therefore, it can be written as

x in( -2, oo)

notice that the bracket is a closed one [()] because the interval is simply greater than -2 not including it. And infinity(oo) is always excluded and hence under the open bracket [i.e ()]
