===================================================

Reason:

Replace x with 4 in each inequality

x > 0 becomes 4 > 0 which is true

x < 7 becomes 4 < 7 which is also true

Both inequalities are true, which confirms x = 4 is a solution.

----------

If you wanted, you can think of x > 0 as 0 < x

Then we have 0 < x and x < 7 become 0 < x < 7

Replacing x with 4 has 0 < 4 < 7 as a true statement.
