SOLUTION: ax+by=u cx+d y=v when d is=[a b c d]=/0 what is the answer

Question 251662: ax+by=u
cx+d y=v when d is=[a b c d]=/0 what is the answer

I think I understand your question. Let's first solve for x and y in terms of a, b, c, d, u, and v.
multiply the first equation by c and the second equation by -a:

This will eliminate the x variable and we can solve for y.

So, y equals
(i)
substituting that into the first equation for x, we get

Solving for x, we get
(ii)
Now we have solve for X and Y in terms of a, b, c, d, u, and v.
-----
Case 1: let d = a.
From (i and ii) we get

-----
case 2: let d = b.
From (i and ii) we get
- ->

-----
case 3: d = c.
From (i and ii) we get

-----
case 4: d = d
From (i and ii) we get

I hope that helps and is what you were looking for.
