Question

Why is 3X 1 unsolvable?​

Answer 1

See below.

Explanation:

I guess the other answer is kind of true, even after you clarified that it's (3x + 1).

BUT, quite often you see something like:

If a function of x, f(x), is (3x + 1) then....

So you might write this as:

f(x) = 3x + 1

And "f(x)" almost always just means "y", because they're going to want you to graph it, so we can say:

y = 3x + 1

And that's certainly an equation we can "solve".

First, we could graph it by generating some points:

(0,1), (1,4), (2,7), etc.

You could graph those points and in a way you've "solved" the equation.

OR, you could "solve for x":

y = 3x + 1 Turn it around:

3x + 1 = y Subtract 1 from both sides:

3x = y - 1 And finally, divide by 3:

x = (y-1)/3

So no, you can't get a number out of that, but you can "solve" it a couple of ways if you consider it a "function of x."

I don't know if that helps. Is there any other context?

Answer 2

because you can't do anything to the equation because there is no way to subtract anything or divion or anything
