What must be true about two integers that
combine to equal zero?

Step-by-step explanation:

Let's represent the two integers as variables and .

We know that these two integers sum to 0, so we can write it as the following equation:

Subtracting from both sides will give you the following:

Based on this, we can say that if two integers sum to equal zero, then they must be opposites of each other, for example, and .

Step-by-step explanation:

BOTH integers should be additive inverse of each other.

For example:

Let us consider an integer 5

Its additive inverse = - 5

Therefore,

5 + (-5) = 5 - 5 = 0

not really sure

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
