    36>= 1-5z > -22

    First break it up into 2 inequalities

    36>= 1-5z and 1-5z > -22

    Next solve each separately

    36>= 1-5z

    35>= -5z

    -7<= z

    1-5z > -22

    -5z > -23

    z< 23/5

    so ur answer is : 23/5> z >= -7

    36>=(1-5z)>-22

    Subtract 1 from all terms,

    35>=-5z>-23

    Divide by (-5), remember to change the direction of inequality since you're dividing by a negative number.

    -7<=z<(23/5)
