Answer 2

You can simplify x + 2x as 3x because it would lead to the same result. Like if x was 6, 6 + 6 x 2 (12 = 18. The result would be the same as 6 x 3.

Answer 3

Ok so would it be the second one?

Answer 4

Y is a little different. You're subtracting y from y3, so the result would be y2.

Answer 5

O never mind it is the second one. :P
