Answer:

CD = 38

Explanation:

BC + CD = BD

8x + 8 + 6x - 28 = 10x + 24

8x + 6x + 8 - 28 = 10x + 24 {Combine like terms}

14x - 20 = 10x + 24 { Add 20 to both sides}

14x = 10x + 24 + 20

14x = 10x + 44 {Subtract 10x form both sides}

14x - 10x = 44

4x = 44 {Divide both sides by 4}

x = 44/4

x = 11

CD = 6x - 28 = 6*11 - 28 = 66 - 28 = 38
