It is impossible to solve, so the best option is to isolate.

Explanation:

You can't solve this equation because there are two variables.

With more than one variable undefined, there can be an infinite amount of possibilities. E.g.:

3x^2+n-44=0

3(2)^2+(32)-44=0

12+32-44=0

Or we can sub in...

3x^2+n-44=0

3(5)^2+(~31)-44=0

75-31-44=0

As you can see, there is an unlimited amount of variables that we can have. Unless we restrict one of them to a set value, then it is impossible to solve. The only thing we can do is to isolate and solve for that.

However, solving implies we determine the exact value of a variable, in which we can't do that here.

If we were to isolate, it would be like this:

3x^2+n-44=0

3x^2=44-n

x^2=(n-44)/3

x=((n-44)/3)^2

And for n...

3x^2+n-44=0

3x^2+n=44

n=44-3x^2

Hope this helps :)
