write a system of equations with the solution (4,-3)
----------------------------------------------------------------------------------------------------------------------------
OK....this isn't so tough to do..... we only need two equations!!
One equation could be
5x - 2y = 26
The other could be
1x - 1y = 7
For reasons I won't go into, I know there is a unique solution to this. And our unique solution is (4, -3).
Check this for yourself/ Also.......this isn't the "only" system that "works." (We could have an infinite number of them!!)
