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

Given: 2X + 2Y = 42X + Y = 42/2X + Y = 211 + 20 =212 + 19 =213 + 18 =214 + 17 =215 + 16 =216 + 15 =217 + 14 =218 + 13 =219 + 12 =2110 + 11 =21Given: XY = 1048 x 13 = 104X=8, 13Y=13, 8
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

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
