Let the number be x


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


[tex] |x--2|=4[/tex]


[tex] |x+2|=4[/tex]


So either



[tex] (x+2)=4[/tex]


[tex] x=4-2=2[/tex]


Or


[tex] -(x+2)=4[/tex]


[tex] x+2=-4[/tex]



[tex] x=-4-2[/tex]



[tex] x=-6[/tex]



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


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