Answer:

the first one should be 2 because

if you put 2 it would look like this:

7x + 2 = 7x + 2

and if you answer it or try to simplify

7x + 2 = 7x + 2 or 7x + 2 = 7x + 2

- 2 - 2 -7x -7x

7x = 7x 2 = 2

/7 /7

x = x

and for the second one could be any number but 2

to prove this lets choose 5

and now to solve:

7x + 2 = 7x + 5 or 7x + 2 = 7x + 5

-7x -7x - 2 - 2

2 ≠ 5 7x = 7x + 3

-7x -7x

0 ≠ 3
