Answer 2

Solving the System of Equations:

To solve the system of equations provided, we will use the information from the search results.

The system of equations is as follows: 1. 2x - y = 7 2. x^2 - xy = 12

Let's solve for the values of x and y using the provided information.

First, we'll use the information from Source to solve the system of equations.

The snippet from Source provides the following equations: 1. 2x - y = 7 2. x^2 - xy = 12

Now, let's proceed with solving the system of equations using the provided information.
