Answer 1

Answer:

d is the correct answer

Answer 2

Answer:

(c) & (b) is the correct answer.

Step-by-step explanation:

It is because x + x =2x

In (a), answer will be 2x. So it is wrong.

In (b), it will be x - x = 0. So it is correct.

In (c), it will be x + x = 2x. So it is correct.

In (d), it will be x = -x, because the negative sign is outside of the absolute. So it is wrong.
