Answer 1

$2(1+x) \ \textgreater \ x+8$
$2+2x \ \textgreater \ x+8$
$2x-x\ \textgreater \ 8-2$
$x \ \textgreater \ 6$

Hence it must be D) 7&8

Answer 2

Hello! And thank you for your question!

2 + 2x > x + 8

First subtract 2 from both sides:

2x > x + 8 - 2

Next simplify x + 8 - 2:

2x > x + 6

Then subtract x:

2x - x > 6

Finally simplify:

x > 6

Final Answer:

x > 6 / D) 7 & 8
