If \(x+y=z\) and \(x=y\), then which of the following must be true EXCEPT
A. \(2x+2y=2z\)
B. \(x-y=0\)
C. \(x-z=y-z\)
D. \(x=\frac{z}{2}\)
E. \(z-y=2x\)
Kudos for the right answer and explanation

A) Dividing both sides by 2
We get x+y=z - out
B) Adding y on both sides
x=y - out
C) Adding z on both sides
x=y - out
D) Putting the value of y in x=y=z
2x = z
x=z/2 - out
E) Putting the value of y in z-y=2x
z -x = 2x
z=3x - Not true and Hence the answer.
We get x+y=z - out
B) Adding y on both sides
x=y - out
C) Adding z on both sides
x=y - out
D) Putting the value of y in x=y=z

x=z/2 - out
E) Putting the value of y in z-y=2x
z -x = 2x

x= 2
y=2
therefore z=4
just substitute the defined properties and get the answers
Answer E
y=2
therefore z=4
just substitute the defined properties and get the answers
Answer E
