    Step-by-step explanation:

    -4 > x / - 7 ... multiply both sides by - 7, and flip the sign

    -4 * - 7 < = x

    28 28

    yes, they are both the same.

    28 < x ... this is saying that 28 is less then x

    x > 28 ... this is saying that x is greater then 28

    so there both saying the same thing
