You can put this solution on YOUR website!
x + 5y = 10 --(1) \r
\n" ); document.write( "\n" ); document.write( "-2x -10y = -20 --(2)\r
\n" ); document.write( "\n" ); document.write( "(1) x 2 = 2x + 10y = 20 --(3)\r
\n" ); document.write( "\n" ); document.write( "(3) + (2) = 0\r
\n" ); document.write( "\n" ); document.write( "The solution to these two equations is 0. I'll let you figure out why.
