    One

    AB + BC = 28

    AB = 10

    10 + BC = 28

    BC = 28 - 10

    BC = 18

    Two

    AB + BC = AC

    AB = 6x

    BC = 8x

    6x + 8x = 42

    14x = 42

    x = 42/14 = 3

    Three

    AB = 2x - 1

    BC = 3x + 5

    AB + BC = 24

    2x - 1 + 3x + 5 = 24

    5x + 4 = 24

    5x = 24 - 4

    5x = 20

    x = 20/5

    x = 4

    AB = 2x - 1

    AB = 2*4 - 1

    AB = 7
