Answer by HyperBrain(694) About Me  (Show Source):
You can put this solution on YOUR website!
10x+%2B+2y+=+7
But if you substitute y+=+-5x+%2B+3,
10x%2B2%28-5x%2B3%29=7
10x%2B%28-10x%2B6%29=7
%2810x-10x%29%2B6=7
0%2B6=7
6=7 ????

The equation lead into a false statement.
therefore, there is no solution
