Answer 1

(x, y) = (1 7/9, -2 1/9)

Explanation:

If all you want is a solution, an appropriate calculator can provide that. The attachment shows the result of using a graphing calculator. (We have to know the fraction equivalents of the decimal values shown.)

The solution to the system is ...

(x, y) = (1 7/9, -2 1/9)

__

The solution is approximately (2, -2).
