Question 210564
Write a system of linear equations in two variables having {(-2, 7)} as a solution set. (More than one system is possible.) Make sure that your system has two equations with two variables!
-------------------------------------------------
Since:
2*-2 + 3*7 = 17
and
-2 - 2*7 = -16
------------------------
the system:
2x + 3y = 17
x - 2y = -16
---
will have solution (-2,7)
