5x + 3y - 2 - x + y + 2 = 4x + 4y = 4(x + y)
If: x+2 = y+6 Then: y = x-4
If th equestion meant: (x+y+z)^2The expansion is:(x+y+z)^2= x^2+2xy+y^2+2yz+z^2+2zx
Only when X or Y = 0 That is because (x + y) squared = x^2 + 2xy + y^2 x^2 + 2xy + y^2 = x^2 + y^2 when x or y = 0
y = x + 2 y = -x + 4 x + 2 = -x + 4 2x + 2 = 4 2x = 2 x = 1 y = x + 2 y = 1 + 2 y = 3 (1, 3)
x + 2 = y x - y + y - x = 0, even though what is y equivalent. Are you sure, you are looking for something else?
the Y in the sentence X plus Y equals 5 is Y=3 or 2 if the X is 2 or 3

(x^2 - y^2)
It is difficult to tell because this site uses a useless browser: one which cannot accept most mathematical symbols. So all we can see of the given equation is "y x2 10x plus 30", and the options appear as "y (x 5)2 plus 55 y (x 5)2 plus 30 y (x 5)2 5 y (x 5)2 plus 5".If the equation is y = x^2 - 10x + 30 then the answer is y = (x - 5) ^2 + 5.
(x+y)2
x = 14
