In normal arithmetic, x = 0
x (x+5) = 6 X equals 1.
In NORMAL arithmetic, x equals 0
y = x This is a line and a function. Function values are y values.
The domain is the x values, so x = 0 to 10. The range is the y values, so y = 0 to 25.

10.

Because the variables of x and a have different values so they can't be equal.
First column, of x values, is the domain of x - whatever that may be. Second column, of function values is always 3.
No. In fact, under normal rules of operation, x-y equals y-x only when x = y.
(x, y) = (-3, -3) or (3, 3)
Find an equation of variation where y varies directly as x. One pair of values is y = 80 when x = 40
