x = 4
Step-by-step explanation:
Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.
Taking , we can simplify this just to make it a bit more professional, to say (We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).
Now, we can really start by dividing both sides by 6, to get , and then divide both sides by x to get .
So, the answer of this quadratic equation is x = 4.
