xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc

x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
the answer is x(3+y)
mid point of xy
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
true
x+xy=8 xy=-x+8 y=-1+8/x
6
x and y are being combined using a binary operation called "plus" and the result is xy.
xy + xy = 2xy
It cannot be a property since it is not generally true!
Yes
between X and Y
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc
It is an expression in the form of: xy+7
