It would be 5.

Reasoning:

Let's call the unknown value "x." To solve this, just add 9 to both sides of the equation.

The reason for adding 9 to both sides is to cancel out the -9 on the side with the unknown value, this would give you the answer once simplified in this way.

Step 1:

-4 = __ - 9

Step 2:

-4 = x - 9

Step 3:

-4 +9 = x - 9+9

Step 4:

5 = x
