y=-3 is this right.

  • algebra - ,

    3/4(5x-1/2)-5/3<1/3
    3/4(5x-1/2) < 1/3 + 5/3
    3/4(5x-1/2) < 2 , now multiply by 4
    3(5x - 1/2) < 8 , now expand
    15x - 3/2 < 8 , times 2
    30x - 3 < 16
    30x < 19
    x < 19/30


    your second problem:
    6y+2y<-24
    8y ≤ - 24
    y ≤ -3
