(x−y)/z=1 with x=1
This means:
(1−y)/z=1
Multiply both sides by z:
1−y=z
z can't be 0 since it is in the denominator.
And only y=1 makes z=0
Therefore, y=1 is NOT a possible value.
Answer: B

Bunuel
\(\frac{x-y}{z}= 1\)
solving this equation, we get
x-y = z
when x =1, we get
1 - y = z
1 - z = y
z cannot take the value of 0 (zero), as it’s in denominator, and the term becomes undefined.
so, when z = 0, y = 1.
Hence, the value y cannot take is 1.
Option B
