Question 548925: How do I solve -x/5 = 1/16 using the multiplication principle. Examples in my textbook look like 5x = 25 or 2/3 = -5/6y, but nothing in which the unknown number is in the actual fraction and this confuses me.
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
There are different ways of writing the same number that are equivalent.
For example
There are different ways to write the same expression that are equivalent.
When the coefficient of a variable is 1 or -1, it does not need to be written out.
So, and
Just as ,
if you wrote x instead of 3,
The x is really multiplied times -1/5. By writing it on top of the fraction bar, they are saving ink by avoiding to write the 1.
When you write as -5/6y, you mean -=
To solve or (they are really the same equation),
you can multiply both sides of the equation times , knowing that the resulting equation will have exactly the same solutions. So, you get

and that simplifies to
