Thank you... I really dont understand this

Answer 1

here you go :) The correct answer for #2 is x and #3 is x R, x < -2. #1 in the photo is correct.

Answer 2

`x-5>-2`;Option third is correct

`x - 5 > -10.`;Option two is correct

`5 > x + 7`;Option two is correct

Step-by-step explanation:

In case
`x-5>-2` simply the expression we will get

`x>-2+5=x>3`

Hence, option third that is
`(x| x R,x>3)`

In case
`x - 5 > -10.` simplify the expression we will get

`x>-10+5\\x>-5`

Hence, Option two is correct

`(x| x R,x>-5)`

In case
`5 > x + 7` simplify the expression we will get

`5>x+7\\5-7>x\\-2>x\\x<-2`

Hence, Option two is correct
