    Step-by-step explanation:

    12x+7<-11 and 5x-8 is greater than or equal to 40

    To solve

    12x+7<-11

    Collect like terms

    12x=-11-7

    12x=-18

    Divide through by 12

    -18/12

    =--3/2 or - 1 1/2

    5x-8 greater than 40

    5x=40+8

    5x=48

    Divide through by 5

    =48/5

    9 3/5
