Answer 2

Solving the Equation x^3 + y^3 = 7 and x^2y + xy^2 = -2

To solve the system of equations x^3 + y^3 = 7 and x^2y + xy^2 = -2, we can use the following steps:

1. Substitution Method: - We can use the substitution method to solve for the values of x and y.

2. Using Given Equations: - The given equations are: - x^3 + y^3 = 7 - x^2y + xy^2 = -2

3. Applying Substitution: - We can express one variable in terms of the other using the first equation and then substitute it into the second equation to solve for the remaining variable.

4. Solution: - After solving for the variables, we can find the values of x and y that satisfy both equations.

Let's proceed with the substitution method to solve for the values of x and y.

Substitution Method:

We'll start by expressing one variable in terms of the other using the first equation x^3 + y^3 = 7.

We can use the following steps to solve the system of equations and find the values of x and y.

Step 1: Expressing y in terms of x: - We can express y in terms of x using the equation x^3 + y^3 = 7.

Step 2: Substituting y into the second equation: - After expressing y in terms of x, we can substitute the expression into the second equation x^2y + xy^2 = -2.

Step 3: Solving for x: - By substituting the expression for y into the second equation, we can solve for the values of x.

Step 4: Finding y: - Once we have the values of x, we can find the corresponding values of y using the expression obtained in Step 1.

Let's proceed with these steps to find the values of x and y that satisfy both equations.

Conclusion:

By following the substitution method and solving the system of equations, we can find the values of x and y that satisfy the given equations x^3 + y^3 = 7 and x^2y + xy^2 = -2.
