Answer:


x = 3

Explanation:

Since points, A, B, C, D and E are collinear, AB = x + 7, BC = 2x, AC = 16, therefore:


AB + BC = AC


(x + 7) + 2x = 16

Solve for x


x + 7 + 2x = 16


3x + 7 = 16

Subtract both sides by 7


3x + 7 - 7 = 16 - 7


3x = 9

Divide both sides by 3


(3x)/(3) = (9)/(3)


x = 3
