What is (are) the x value(s) that solve the system of equations y=x 2 and y=-2 x-1 ?

Question

Accepted Answer

Step:1 ：We are given the system of equations: (y = x^2) and (y = -2x - 1).Step:2 ：We need to find the value of (x) that satisfies both equations simultaneously. This means we need to set the two equations equal to each other and solve for (x).Step:3 ：Setting the two equations equal to each other gives us (x^2 = -2x - 1).Step:4 ：Solving this equation gives us the solution (x = -1).Step:5 ：Therefore, the solution to the system of equations is (x = -1).Step:6 ：Final Answer: (boxed{-1})
