Algebra.Com's Answer #36261 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! X-2Y=-10 OR X=2Y-10 NOW SUBSTITUTING (2Y-10) FOR X IN THE OTHER EQUATION WE GET .5(2Y-10)-5Y=19 OR Y-5-5Y=19 OR -4Y=24 OR Y=24/-4 OR Y=-6 \r \n" ); document.write( "\n" ); document.write( "THE X-2(-6)=-10 OR X+12=-10 OR X=-10-12 OR X=-22\r \n" ); document.write( "\n" ); document.write( "PROOF .5(-22)-5*-6=19 OR -11+30=19 OR 19=19 \n" ); document.write( " |
