Algebra.Com's Answer #65745 by checkley75(3666) ![]() You can put this solution on YOUR website! 3x-y=0 or -y=-3x or y=3x now substitute 3x for y in the othere equation \n" ); document.write( "3x+3x=6 \n" ); document.write( "6x=6 \n" ); document.write( "x=6/x \n" ); document.write( "x=1 answer. \n" ); document.write( "3*1+y=6 \n" ); document.write( "3+y=6 \n" ); document.write( "y=6-3 \n" ); document.write( "y=3 answer. \n" ); document.write( "proof \n" ); document.write( "3*1-3=0 \n" ); document.write( "0=0 \n" ); document.write( " |
