(1) $\"x+-+3y+=+9\"$
\n" ); document.write( "(2) $\"5x+-+15y+=+45\"$
\n" ); document.write( "----------
\n" ); document.write( "Multiply both sides of (1) by $\"5\"$
\n" ); document.write( "(1) $\"5x+-+15y+=+45\"$
\n" ); document.write( "(1) is identical to (2), so it's not a system of
\n" ); document.write( "equations, it's the same equation twice \n" ); document.write( "
