Answer:
\boldsymbol{(-\infty, 9)}

Work Shown

5x+1 > 7x-17

5x-7x > -17-1

-2x > -18

x < -18/(-2)

x < 9

The inequality sign flips when dividing both sides by a negative value.

The inequality
\text{x} < 9 is the same as
-\infty < \text{x} < 9 and then that condenses to the interval notation
(-\infty, 9)

Use curved parenthesis so you exclude the endpoint.
