Question

Fill in the blank: $-4+\_\_\_\hspace{0.17em}=-12$

Answer 1

You need to find the integer such that when you add it with the integer $-4$, the answer is $-12$.

So, $(-4)+a=-12$ (let $a$ be any integer)

$a=-12+4$

$a=-8$

Verify:$(-4)+\hspace{0.17em}(-8)=-4-8=-12$

Hence, the answer is $-8$
