    x < - 1/4

    Step-by-step explanation:

    -3/5x + 1/5 > 7/20

    Subtract 1/5 from each side

    -3/5x + 1/5-1/5 > 7/20-1/5

    Get a common denominator

    -3/5x > 7/20 - 1/5*4/4

    -3/5 x > 7/20 - 4/20

    -3/5x > 3/20

    Multiply by - 5/3 to isolate x

    When we multiply by a negative it flips the inequality

    -5/3 * -3/5x < - 5/3 * 3/20

    x < - 5/20

    x < - 1/4
