Yes, Lets look at
2x=x
In order to move the x over to the other side of the equation, we will have to subtract it.
This means our equation will now look like:
x=0
Another example:
-x=9x
Now that the x is negative, we have to do the opposite of a negative, which is a positive, which means we would have to add an x on both sides.
Our equation will now look like:
0=10x
