Algebra.Com's Answer #38337 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! 2x + y = 5; (3, -1)\r \n" ); document.write( "\n" ); document.write( "I assume you are being asked to see if (x,y)=(3,-1) is a solution to the equation. To do this, let x=3 and y=-1, simplify and see if both sides equal. If they do, then it is, if they don't then it isn't. \n" ); document.write( "2(3)+(-1)=5 \n" ); document.write( "6-1=5 \n" ); document.write( "5=5 \n" ); document.write( "Yes (3,-1) is a solution to the equation 2x+y=5. \n" ); document.write( "Happy Calculating!!! \n" ); document.write( " |
