An equation of a line (Linear function, first-degree function). It's a line with a slope of 1/3, meaning for every 3 increase in x, increases by 1.
Y = 15 15 divided by 5 = 3
It depends on how y depends on x.
Y = 4/x^2
If x+y = 3 and y times x = 2 then y = 1.
You would need one more equation relation x and y to solve for both of them.

1.5
x=y
x=4 y=x+3 y=4+3 y=7

x2 / y = (6)2 /2 = 36/2 = 18
One simple solution is y = (x + 5/2)*(x - 2)*(x - 3/2) You can expand that into its cubic form, if you wish.
6
(x, y) = (-3, -3) or (3, 3)
It is x = 2 and y = 1
Y = 15 15 divided by 5 = 3
It depends on how y depends on x.
