1.) No Solutions, Inconsistent System
x + y = 5
-
x + y = 15
0 = - 10 (which is false)
2.) One Solution, Independent System
x - 2y = 4
3y = 1
y = 1/3
x + 1/3 = 15/3
x = 14/3
3.) Infinitely many solutions, Dependent System
3x - 3y = 15
-2x - 2y = -10
2x + 2y = 10
y = 5 - x (from x + y = 5, where y is isolated)
2x + 2(5 - x) = 10
2x + 10 - 2x = 10
10 = 10
x = 5 - y (from x + y = 5, where x is isolated)
2(5 - y) + 2y = 10
10 - 2y + 2y = 10
Either way, you will get 10 if you isolate x or y.
No need for 100 load :D
