Is there an "X" in the problem somewhere? You have -13 > -5 + 2 > -28.

If the x is by the -5, then we have -13 > -5x + 2 > -28

Like regular algebra: subtract two from both sides

-13 - 2 > -5x + 2 - 2 > -28 - 2

-15 > -5x > -30

Now, divided by -5 (REMEMBER WHEN YOU DIVIDED BY NEGATIVE, THE > SIGN CHANGES TO <)

3 < X < 6

Correct graph would be a unfilled circle on the x = 3 line and would be a solid line to the number x = 6. at the X = 6, there would be another unfilled circle (meaning NOT EQUAL TO).
