if x + y = w, then x = w - y
x - y = w Add y to both sides: x = w + y
w(x + y)
(x + y)(x + y)(x + y)
c
if x + y = w, then x = w - y
w=x-y w+y=x
x - y = w Add y to both sides: x = w + y
The answer is 5x+3y. (5 xs and 3 ys)
w(x + y)
(x + y)(x + y)(x + y)
The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
It is the same. The equation "x + y" is the exact same as "x + y." There is no difference.

y += x means the value y+x is first calculated, and the resulting value is then assigned to y. It is equivalent to y = y+x
If the expressions are w, x, y, z then to show that no two of them are equal is shown by(w-x)*(w-y)*(w-z)*(x-y)*(x-z)*(y-z) ≠0.Note that w .ne. x AND x .ne. y AND y .ne. z is not enough since it is possible for x = z.
