Algebra.Com's Answer #183061 by MRperkins(300)![]() ![]() You can put this solution on YOUR website! x+2y=3 \n" ); document.write( "4x+5y=6 \n" ); document.write( "x=3-2y \n" ); document.write( "4(3-2y)+5y=6 \n" ); document.write( "12-8y+5y=6 \n" ); document.write( "12-3y=6 \n" ); document.write( "-3y=-6 \n" ); document.write( "y=2 \n" ); document.write( "x+2(2)=3 \n" ); document.write( "x+4=3 \n" ); document.write( "x=-1 \n" ); document.write( "check solution x=-1, y=2 or (-1,2) written as a coordinate point. \n" ); document.write( "-1+2(2)=3 \n" ); document.write( "3=3 so it works in this equation\r \n" ); document.write( "\n" ); document.write( "4(-1)+5(2)=6 \n" ); document.write( "6=6 so it works in this equation. Therefore, your solution is (-1,2)\r \n" ); document.write( "\n" ); document.write( "Email me at justin.sheppard.tech@hotmail.com for more help. We can even set up an online whiteboard to practice problems. \n" ); document.write( "Good luck \n" ); document.write( "Justin \n" ); document.write( " |
