A little help:
7m − 5 − 13m = 25
I got down to
-6m - 5= 25
I know you take the 5 and put it on the other side of the 25 but I cant remember if you add the 5 or subtract it

A little help:
7m − 5 − 13m = 25
I got down to 
-6m - 5= 25
I know you take the 5 and put it on the other side of the 25 but I cant remember if you add the 5 or subtract it

you don't *really* move the 5
with an equation (to keep it equal) you can *do the same thing to both sides*
For example we could add + 5 to both sides, like this

-6m - 5 + 5= 25+5
now simplify

You could (but don't want to) add -5 to both sides:
-6m -5 - 5 = 25 - 5
but that is not helpful, because you get  -6m - 10 = 20  (not what you want)
