Question

C is between B and D
BC = 8x +13
CD= 12x -73
BD =320
find the value of x

Answer 1

x = 19

Explanation:

Since C is between B and D , then

BC + CD = BD , substitute values

8x + 13 + 12x - 73 = 320 , that is

20x - 60 = 320 ( add 60 to both sides )

20x = 380 ( divide both sides by 20 )

x = 19
