Question

Difference of a number and -3 is 6. what is the number

Answer 1

Let x = the number we are looking for:

Difference means that we subtract:


`x-(-3)=6`

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


`x+3=6`

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


`x=3`

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