8
x + y = 6 (A)
x - y = 2 (B)
Eqn (a) + Eqn (B): 2x = 8 => x = 8/2 = 4
Substituting this value in to Eqn A: 4 + y = 6 => y = 2
So (x, y) = (4, 2).
x and y are being combined using a binary operation called "plus" and the result is xy.
mid point of xy
x+xy=8 xy=-x+8 y=-1+8/x
between X and Y
x = 6y over (y-6)
x and y are being combined using a binary operation called "plus" and the result is xy.
mid point of xy
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
true
It equals y+1
x+xy=8 xy=-x+8 y=-1+8/x
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
