Question #9234f

1 Answer

Jan 29, 2018

No solutions for $x, y$ $x,y$ .

Explanation:

No need to use matrices here.

$2 x - y = 10$ $2x-y=10$ $(1)$ $(1)$

$2 y - x - 15 = 0$ $2y-x-15=0$ $(2)$ $(2)$

From, $(2)$ $(2)$ , we can rewrite this into $2 y - x = 15$ $2y-x=15$ .

Now here, from $(1)$ $(1)$ and $(2)$ $(2)$ we conclude that $10 = 15$ $10=15$ . But we clearly know that $10 \neq 15$ $10!=15$ .

So, we can say that there are no solutions for $x, y$ $x,y$ .
