Answer:
-2.2 = x
Step-by-step 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:
[tex]\frac{-8.58}{x}[/tex] = 3.9
What we're going to do here is multiply x on both sides.
[tex]\frac{ (x)-8.58}{x}[/tex] = 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!
