Answer

$(0,0)$ $(1,1)$

Work Step by Step

Given the system of equations: 1. $x - y^2 = 0$ 2. $y - x^2 = 0$ It asks to find all solutions. Substitute $y = x^2$ $x = (x^2)^2 = 0$ $x - x^4 = 0$ $x(1-x^3) = 0$ $x = 0, 1$ Substitute the values into the equation $y - 0^2 = 0$ $y = 0$ $y - 1^2 = 0$ $y = 1$ All solutions: $(0,0)$ $(1,1)$
