The integer that makes the expression, (____ + -3 = -4), true is -1.
According to the question,
We have the following expression:
__ + (-3) = -4
Now, let's take the integer to be filled in the blank as x.
Now, putting x in the given expression:
x + (-3) = -4
x = -4+3 (3 was negative on the left hand side. So, it is positive on the right hand side.)
x = -1
(More to know: when two numbers are given with two different signs then the smaller number is subtracted from the larger number but the sign remains of the number which is larger.)
Hence, the integer that makes the given addition sentence true is -1.
