Answer:

  1) x > 9

Step-by-step explanation:

You want the solution to the inequality 7 -2/3x < x -8.

Solution

Adding 8 to both sides, we get ...

  15 -2/3x < x

Adding 2/3x to both sides gives ...

  15 < 5/3x

Multiplying both sides by 3/5, we have ...

  9 < x

Rearranging to put x on the left gives ...

  x > 9 . . . . . matches choice 1
