Answer 2

Solving the System of Equations

To solve the system of equations x + y = 2 and x^2 + 4y = 8, we can use the substitution method.

First, we can solve the first equation for x: x = 2 - y.

Then, we can substitute this value of x into the second equation: (2 - y)^2 + 4y = 8.

Expanding and simplifying the equation gives us a quadratic equation in terms of y, which we can solve to find the value of y. Once we have the value of y, we can substitute it back into the equation x = 2 - y to find the value of x.

Let's proceed with solving the quadratic equation to find the values of x and y.

Solving the Quadratic Equation

The quadratic equation obtained from the substitution is: (2 - y)^2 + 4y = 8.

Solving this equation will give us the value of y, which we can then use to find the value of x.

Solution

After solving the quadratic equation, we find that the solutions for the system of equations are: y = 1 and x = 1.

Therefore, the solution to the system of equations x + y = 2 and x^2 + 4y = 8 is: x = 1 and y = 1.
