I see that the addition method is also called the elimination method. I don't understand which one (x or Y) to choose to eliminate first. Also,if you choose to multiple to create a cancellation, how do you determine what to multiply by? ex.
2x +5y =6
3x - 2y = 6x +2 This is a "you try it". I don't get how they eliminated the 6x to solve the system, as they put it. So many questions...so little time.
