    - 2 x > 1/9
    divide both sides by - 2 AND change direction of arrow
    x < -1/18
    when you multiply (divide) both sides of an inequality by a negative, you reverse the arrow

    Thank you

    Think about
    -x > 1
    that would be everything to the left of -1

    Now do the algebra, multiply both sides by -1 and reverse arrow:
    x < -1 sure enough
