For this case we must find the solution set of the given inequalities:

Inequality 1:

[tex]x + 2 <5[/tex]

Subtracting 2 from both sides of the inequality we have:

[tex]x <5-2\\x <3[/tex]

Thus, the solution is given by all values of x less than 3.

Inequality 2:

[tex]x-7> -6[/tex]

Adding 7 to both sides of the inequality we have:

[tex]x> -6 + 7\\x> 1[/tex]

Thus, the solution is given by all values of x greater than 1.

Therefore, the solution set is given by all real numbers.

Answer:

All real numbers
