Answer:

-2.2 = x

Explanation:

So, we're trying to find x in our equation here. In order to do this, we need to isolate the variable.

-8.58 / ___ = 3.9

It's easier for me to write out the equation like this:


(-8.58)/(x) = 3.9

What we're going to do here is multiply x on both sides.


( (x)-8.58)/(x) = 3.9 (x)

The x with the fraction cancels out, leaving -8.58. 3.9 times x is 3.9x.

Our equation now looks like this:

-8.58 = 3.9x We now divide 3.9 from both sides. (3.9x divided by 3.9

-2.2 = x cancels out, leaving us with x).

We have now found our answer!
