Jennifer pose la question :
Could I get an answer to this one: 2x+5y=36
3x+2y=32 I have to use the Elimination method, as I already know how to do Substitution. How do I begin and show my work? I'm attempting to eliminate the values for y.

Jason Bussey pose la question :
The linear systems with the following pattern all have the same solution. Is their some kind of reasoning as to why this is so? 2x+3y=4
3x+4y=5 4x+5y=6
5x+6y=7 The solution is always x=-1, y=2 Thank you
Jason
