Question

write the integer which is 4 more than its additive inverse

Answer 1

Let the integer be x, its additive integer will be -x.

Now the integer is 4 more than its additive inverse, means, x is 4 more than -x, it means,

if we add 4 to its additive inverse -x, we get, the integer x.

Thus, the expression will be

x = -x + 4

$\Rightarrow$ x + x = 4

$\Rightarrow$ 2x = 4

$\Rightarrow$ x = 2.

Hence, the answer.
