: I'm stuck on this problem:
a-b
_____ = -d solve for b
c

I multiplied both sides by c
a-b = -d(c)
then i subtracted a from both sides.
-b = -d(c) - a
The answer my book gives is b = cd + a
How do I make the b, d and a positive? HELP!!!

You did a great job! Just multiply the entire equation through by (-1).
THis will get rid of all of the negatives, leaving all positive terms.

---------------
-b = -cd -a
Multiply both sides by -1 to get:
b = cd+a
