Answer:
-2
Step-by-step explanation:
Well if we break -2x apart we see that it's really just -2 × x.
Now, let's say you completely forget this you can think of it like this:
-2x is, -2 and x.
Between these two terms x is the variable leaving -2.
You can try the same thing with these:
5x is ?
-9x is ?
50x is ?
