-19x+1 > (or equal to) -20x-4>-9x+18

Make three inequalities:

-19x+1 > -20x-4     -20x-4 > -9x+18   -19x+1 > -9x+18
     x > -5           -11x > 22          -9x > 17
                         x < -2            x < -1 8/9 

The third one is not necessary since the second one guarantess it.

Turn the first one around

-5 > x  and put it together with x < -2

and get

        -5 < x < -2
