Adding all vakus in data set and divide by the number of values in the data set
The answer si that the first ten odd integers are all even. Maybe this is really a fact but not a conjecture
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0
y^2-3y=0
y(y-3)=0
y1=0 -----------y2=3
