3xy/xy+x xy+x factors to just x(y) right?
dumbcow
  • dumbcow
is the denominator (xy+x)
anonymous
  • anonymous
which would then cancle with the xy on top leaving only 3. yes dumb
dumbcow
  • dumbcow
\[\frac{3xy}{xy+x} = \frac{3xy}{x(y+1)} = \frac{3y}{y+1}\]
dumbcow
  • dumbcow
only the x cancels

hummmm..

Oh you ment 3xy/(xy+x) :)
dumbcow
  • dumbcow
when you factor something out, divide by each term xy/x = y x/x = 1
