Answer:

-1/5 < x < 3

Explanation:

The first step I would take would be to subtract 1 from both sides of the equation. You end up with:

|7-5x| < 8

Because this is an absolute value inequality, there would be two outputs when removing the absolute value:

7-5x < 8

and

7-5x > -8

We can use algebra to solve the equations and end up with

5x > -1; x > -1/5

and

5x < 15; x < 3
