Question

D is the midpoint of CE. If CD= 2x+10 and DE =3x-18, find x and CE

x=
CE=

Answer 1

x = 28

CE = 132

Explanation:

|<------------- CE -------------------->|

C-------------------D-------------------E

2x + 10 3x - 18

2x + 10 = 3x - 18

2x - 3x = -18 - 10

-x = -28

x = 28

CE = 2x + 10 + 3x - 18

CE = 2(28) + 10 + 3(28) - 18

CE = 56 + 10 + 84 - 18

CE = 132
