    no solution

    Step-by-step explanation:

    (you do the exact same you'd do in an equation problem. Get x by itself)

    3x+1<2x-2<5x+7

    1 < - x-2 < 5x+7

    3< - x < 5x+9

    3 < - 6x < 9

    - (1/2) > x > - (3/2)

    x can't be bigger than - 3 halves and be smaller than - 1 half, so the answer is no solution
