Question

Which numbers are 4 units from -2 on the number line

Answer 1

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`

Or

`-(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
