Answer 1

b-4>4
add 4 to both the sides
b-4+4>4+4
Could you simplify this?

Answer 2

I'm afraid not.

Answer 3

I'm trying to help out my little cousin and I failed math.

Answer 4

\[b-4+4 > \underline{4+4}\]
let's simplify the left part
what's 4+4?

@zigzagoon

Answer 5

8 haha

Answer 6

good, so we have now
\[x\underline{-4+4}>8\]
now what's -4+4?

Answer 7

0

Answer 8

good so we have
\[x>8\]
it's simplified now :)
let's mark this on the number line

Answer 9

Ah ha. So it is B. (:

Answer 10

I think..

Answer 11

yeah, just draw a line on number line at x=8
since we have y>8
so shade the right of x=8 with a open circle on the line x=8 ( this indicates that 8 is not included)
could you do it now?

Answer 12

Yes, thank you :3

Answer 13

welcome :D did you understand?

Answer 14

Yes I did, thank you.
