Question

X³ + y³ = 1,x + y = 1​

Answer 1

Это к второму если что

Answer 2

You have a system of equations:

1. x³ + y³ = 1
2. x + y = 1

Let's solve this system of equations step by step.

First, we can solve the second equation (x + y = 1) for one of the variables. For example, we can solve for x:

x = 1 - y

Now, substitute this expression for x into the first equation:

(1 - y)³ + y³ = 1

Now, expand and simplify:

(1 - y)³ + y³ = 1 (1 - y)(1 - y)(1 - y) + y³ = 1 (1 - y)(1 - y)(1 - y) = 1 - y³ + y³ = 1

So, the equation (1 - y)(1 - y)(1 - y) = 1 is satisfied for any value of y.

This means there are infinitely many solutions to this system of equations, and they form a curve in the xy-plane. The curve represents all the points (x, y) that satisfy both equations.
