Question

Point D is on line segment CE.Given CD = X, DE = 7, and CE = 2x, determine the numerical length of CD

Answer 1

7

Explanation:

it's correct

Answer 2

CD = 7

Explanation:

Since D is on the line segment CE then

CE = CD + DE , substitute values

2x = x + 7 ( subtract x from both sides )

x = 7

Thus

CD = x = 7
