You can put this solution on YOUR website!
the equations
\n" ); document.write( "(1) \"+-x+%2B+y+=+5+\"
\n" ); document.write( "(2) \"+x+-+y+=+10+\"
\n" ); document.write( "--------------
\n" ); document.write( "(1) \"+y+=+x+%2B+5+\"
\n" ); document.write( "(2) \"+y+=+x+-+10+\"
\n" ); document.write( "There is no solution to these equations
\n" ); document.write( "because they are parallel lines. In order to have a solution,
\n" ); document.write( "they must intersect.
\n" ); document.write( "The coefficient of \"x\" is the slope, and it is \"1\" for both lines
\n" ); document.write( "--------------
\n" ); document.write( "--------------
\n" ); document.write( "(1) \"+-3x+%2B+y+=+5+\"
\n" ); document.write( "(2) \"+-6x+%2B+2y+=+10+\"
\n" ); document.write( "There is no solution here because these are the same equation.
\n" ); document.write( "If you multiply both sides of (1) by \"2\", you get the 2nd equation.
