Question 1012432
For each system, choose the best description of its solution(no solution, unique solution, infinite solutions). If applicable, give the solution.

 x+2y=2       And   -x-2y=6
-x-2y=-2             x+2y=6   
================
 x+2y=2
-x-2y=-2
---------
The 2nd eqn is -1 times the 1st --> dependent --> infinite solutions.
========================================
-x-2y=6
 x+2y=6
--------------- Add
0 = 12 --> inconsistent --> no solution
==================================
It's not clear how the equations are paired.  The other tutor paired them differently.
Don't enter them like that.
