Answer 1

Answer: B

Explanation:

Answer 2

I think it will be D, because you will be decreasing 0.25x and increasing 0.75x, you will add 0.25x to -0.25x to get rid of 0.25x. Then you will need to do the same thing to the other side. You will add 0.25x to 0.75x so you will be increasing 0.75 since you will be adding to it.

Explanation:

X – 0.25x = 0.75x

X-0.25x+0.25x=0.75x+0.25x

X= 1.00x

All you need to do is add 0.25x to both -0.25x and positive 0.75x. That way it will be equal.

So, I believe it will be D
