Whooop!

x2y = k (constant) so 36 x 2 ie 72 is the constant. If x = 3 then y = 72/9 = 8

It is -2y + x2y - 8, which is an expression that cannot be simplified further, not can it be evaluated.

(x2 - 2)(y - 3)

You will get nonsense. You cannot plug x2y + 4 into anything!

3x3 - x2y + 12x - 4y = x2*(3x - y) + 4*(3x - y) = (x2 + 4)*(3x - y)

4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)

y = 2x - x2y = 0Since both quantities on the right side are equal to 'y', they're equal to each other.2x - x2 = 0x (2 - x) = 0x = 0and2 - x = 0x = 2The two points of intersection are (0, 0) and (2, 0) .
