Hi!
As some have replied, the answer is -x. Since the bases (x) are the same, you can subtract the coifficients (the numbers in front of each x).
So, as I saw it written: 1x - 2x is like (1 - 2)(x). -1(x) = -x.
Hope this is clear for you!

Assign a value to x to make it easy. Let's call it 10, for the purposes of this post.
10-(2x10)=-10. Therefore x-2x=-x.

ok so....
x-2x is equal to -x
because you are basically saying that you have 2 negative x's plus a positive x so one of the negatives gets cancelled by the positive one so you are left with only 1 negative x.

x-2x = -x
x is positive and of course -2x so take away 1 from -2x so this is how it makes it -x

It's -x. -3x would be -x-2x

the answer is -x think of it in exploded terms. x-2x is actually x-x-x ... when you start with x and subtract x you have zero... then subtract another x and this gives you -x

1x - 2x
= (1-2)x
= -1x
= -x
