I have little hard time because we did differently. I watched this video and helped me to understant an American way to do the math what ever the way , the answers are always the same.
Some of thier process make good sence ( I thought we should have learned that way ) some of them are complicated ( not simple)
I could not agree with thier answer.
y( 2-a )
----------
= y was their answer. I could not agree with it and my answer is -y .
a- 2
(y)(-a +2) (y) (-1)(a-2)
------------- , --------------------- cross out a-2 and the remaining is y*-1 = -y am I right or worng ?
a-2 a-2
Thank you.
