Let x = the number we are looking for:

Difference means that we subtract:

[tex]x-(-3)=6[/tex]

Two negative signs turn it into one positive sign (a plus):

[tex]x+3=6[/tex]

We need to get x by itself, so we subtract 3 from both sides:

[tex]x=3[/tex]

So now we know that the number we were asked to find is 3.
