Answer:

Step-by-step explanation:

- 6x + 9 > 7x + 74

Treat them as being equal first.

Subtract 9 from both sides.

- 6x + 9 - 9 > 7x + 74 - 9

- 6x > 7x + 65

Subtract 7x from each side

- 6x - 7x > 7x - 7x + 65

- 13x > 65

Divide each side by -13

- 13x / -13  > 65 / -13

x < -5

So x hust be smaller than -5 meaning -6 works but -4 doesn't.
