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.
If x+y = 3 and y times x = 2 then y = 1.
y = 3x y = 3*19 = 57
its so easy work it out your self
It is reflection in the line y = x.
y = -f(x) is a reflection of y = f(x) in the x axis.
reflection in the x-axis
x equals y
Reflection across the y-axis changes the sign of the x - coordinate only, that is, (x, y) becomes (-x, y).
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.
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
x=y
