1. X/Y = Z
if x = 6, y = 2, then z = 3, not even
if x = 6, y = 3, then z = 2, even
<span>2. Z=XY </span>
so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)
<span>Sufficient, as if square of an integer is even ,then the integer is even</span>
I think the answer is the second one! Hope this helps!
-5 + x/22 = -1
+ 5 for both side
x
--- = 4
22
multiply by 4
x = 22(4)
x = 88
