You can put this solution on YOUR website!
5X-2Y=-5
\n" ); document.write( "-5X+Y=3
\n" ); document.write( "-------------
\n" ); document.write( "-Y=-2
\n" ); document.write( "Y=2 ANSWER.
\n" ); document.write( "--------------------------------------
\n" ); document.write( "8X-4Y=16 NOW MULTIPLY THE SECOND EQUATION BY 4 & ADD.
\n" ); document.write( "-8X+4Y=-16
\n" ); document.write( "--------------
\n" ); document.write( "0X+0Y=0 NO SOLUTION AS THESE ARE THE SAME EQUATION WITH 2 UNKNOWNS.
\n" ); document.write( "--------------------------------------
