Answer:

(x, y) = (1, -1)

Explanation:

The augmented matrix of coefficients for these equations is ...


\left[\begin{array}c2&-5&7\\-2&4&-6\end{array}\right]

The row-reduction function of your calculator can find the solution to the system of equations. The result of using that function is ...


\left[\begin{array}cc1&0&1\\0&1&-1\end{array}\right]

This tells you the solution is (x, y) = (1, -1).
