1. Solve for x. Collect xs on the LEFT side. The solution should be presented with x first, the correct inequality symbol, then the number.
5(2x – 7) < -8

    5(2x-7)<-8
    10x -25< -8
    10x< 17
    x<(17/10)
    x<1.7

    I think you only change the sign when you move a negative by multiplication or division, so I think the sign is correct.
    You might want to reference your book though.

    There is an error in the second line.
    Should be:
    10x - 35 < -8

    ah, typo, sorry.
    5(2x-7)<-8
    10x-35<-8
    10x<27
    x<2.7
