X=300+Y
(300+Y)+Y=500
300+2Y=500
2Y=200
Y=100
x+xy=8 xy=-x+8 y=-1+8/x
x and y are being combined using a binary operation called "plus" and the result is xy.
x = 6y over (y-6)
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
18
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
x and y are being combined using a binary operation called "plus" and the result is xy.
It cannot be a property since it is not generally true!
Yes
between X and Y
It is an expression in the form of: xy+7
xy + z
