You can put this solution on YOUR website!
You cannot divide by 0. Doing so is 'undefined'.
.
So any value of 'y' that would make the denominator = 0 cannot be allowed.
.
(18)/(11y) is undefined if
.
11y = 0
.
That only happens when y = 0
.
So, 'y' can take on any value from -infinity to +infinity, except for 0.
