Yes
xy + x + y + 1 = (x + 1)(y + 1).
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
That equals 2xy + 3y which factors to y(2x + 3)
9 plus 7 equals 144. Generally, x plus y = x(x+y).
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
x+xy=8 xy=-x+8 y=-1+8/x
It equals y+1
x and y are being combined using a binary operation called "plus" and the result is xy.
x = 6y over (y-6)
xy = x ÷x y = 1
Yes
between X and Y
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
Y+7=9 equals 2+7=9.
xy + x + y + 1 = (x + 1)(y + 1).
