Transitive property: If 8 equals x and x equals y, then 8 equals y.
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
x equals -12 and y equals 1/4 of -12, so y = -3.
x=y
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.

x=4 y=4
No. In fact, under normal rules of operation, x-y equals y-x only when x = y.
It depends on how y depends on x.
xy = x ÷x y = 1

y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
