    -2 (8x - 4) < 2x + 5

    Expand the brackets.

    -16x + 8 < 2x + 5

    Add - 2x and - 8 on both sides.

    -16x - 2x<5-8

    -18x<-3

    Multiply both sides with - 1 (reverse the inequalty).

    18x>3

    Divide 18 into both sides.

    18x/18>3/18

    x>1/6

    Step-by-step explanation:

    -2 (8x - 4) < 2x + 5

    Distribute

    -16x + 8 < 2x+5

    Add 16x to each side

    -16x+16x + 8 < 2x+16x+5

    8 < 18x + 5

    Subtract 5 from each side

    8-5 <18x

    3 <18x

    Divide by 18

    3/18
    1/6
