What is the other integer if the sum of two integers is -25 and one of them is 30?

Given that the sum of two integers is - 25 and one of them is 30.

Let the unknown integer be x.

Therefore, according to the given question:

→ x + (30) = - 25

Subtracting 30 from both sides, we get:

→ x + 30 - 30 = - 25 - 30

→ x = - 55

Thus, the other integer is - 55.
