Question 604408: I am working on systems of Linear Equations, solving using the addition method
If it is inconsistent we are to state such, if it is dependent we indicate, x, and answer.
I know this should be simple, I cannot get the hang of it, I tried to follow the book, to no avail.
{ x7 + y + 9 = 5
 
5 2
x+9 + y7 = 6
___ ___
2 3
2(x7) + 5(y+9) = 50
3(x+9) + 2(y7) = 36
2x + 5y = 19
3x + 2y = 23
5x + 7y = 42
x = 7y + 42 / 5
I really dont know what I am doing or what I should do at this point. I would deeply appreciate assistance. Thank you!
