    No solution.

    Step-by-step explanation:

    -3> 7x-8 > - 0.2

    Split this into 2 inequalities:

    7x - 8 < - 3 Add 8 to both side:

    7x < 5

    x < 5/7.

    and:

    7x - 8 > - 2 Add 8 to both sides:

    7x > 6

    x > 6/7.

    But x cannot be both less than 5.7 and > 6.7, so No solution.
