Answer:
The numbers are 6 and 14
Step-by-step explanation:
Let the two numbers be x and y
x-y = 8
x+y = 20
Add the two equations
x-y = 8
x+y = 20
-----------------
2x = 28
Divide by 2
2x/2 = 28/2
x = 14
Subtract the two equations
x-y = 8
-x-y = -20
-----------------
-2y = -12
Divide by -2
-2y/-2 = -12/-2
y = 6
The numbers are 6 and 14

Answer:
A) 11
Step-by-step explaination:
CE = 2x - 2
CE = CD + DE
= x + 9
Hence it can be said that,
2x - 2 = x + 9
2x - x = 9 + 2
x = 11
