You can put this solution on YOUR website!
Y=X & Y=-X CANNOT BE TRUE!!!!!! SUBSTITUTING X FOR Y IN THE SECOND EQUATION WE GET X=-X?????????????????????
\n" ); document.write( "-------------------------------
\n" ); document.write( "Y=-X SUBSTITUTING -X FOR Y IN THE SECOND EQUATION WE GET
\n" ); document.write( "-X=X+9
\n" ); document.write( "-X-X=9
\n" ); document.write( "-2X=9
\n" ); document.write( "X=9/-2
\n" ); document.write( "X=-4.5
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "IF THESE ARE LINE EQUATIONS THEN:
