Answer:

x=8

Explanation:

If both of these equations equal the same thing, that means they are equal to each other.

Now, I don't know what the equation is asking, but I assume it's asking to solve for x.

Since the equations equal each other, we can write a new equation:

100-3x=84-x

subtract 84 from both sides

16-3x=-x

add 3x to both sides

16=2x

divide both sides by 2

8=x

So, x=8.

Hope this helps! :)
