Let the number be x

Then the absolute value of the number from -2 should be 4

$|x--2|=4$

$|x+2|=4$

So either

$(x+2)=4$

$x=4-2=2$

$-(x+2)=4$

$x+2=-4$

$x=-4-2$

$x=-6$

[tex] <B>The numbers are 2 and -6</B> [/tex[

They are four units away from -2 on the number line

In the second step you should have subtracted the 2x to move it to the other or side of the equals sign

I don't understand number 8

Norma-Jean [14]

Let's try plugging in some negative numbers. Let's do x=-1. 5+-1=4. So we know that if we put in a negative number for x, then n will be positive. But what if we do a number greater than -5, because 5+-5=0. So let's try x=-6. So 5+(-6)=-1. Hmm. So here it is. We know that any number under -5 will be positive and any number above -5 will be negative.
