You can put this solution on YOUR website!
you cannot answer this, are there are an infinite number of solutions. With 2 unknowns, you need 2 equations...\r

\n" ); document.write( "\n" ); document.write( "to visualise what you have asked, your equation is a straight line and any point on that line satisfies the equation. Given a second straightline, they will intersect each other at one point, and that will give you your solution for x and y.\r
