Algebra.Com's Answer #213024 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! Where is the triangle for your chosen category? \n" ); document.write( "Save a few steps since there are only three y choices \n" ); document.write( "Try 7 for y first \n" ); document.write( "7=x-2 \n" ); document.write( "9=x \n" ); document.write( "We just eliminated a and b \n" ); document.write( "Try 2 for 2 \n" ); document.write( "2=x-2 \n" ); document.write( "4=x \n" ); document.write( "That doesn't work either \n" ); document.write( "-7=x-2 \n" ); document.write( "Add 2 \n" ); document.write( "-5=x \n" ); document.write( "That works \n" ); document.write( "So the answer must d) (-5,-7) \n" ); document.write( "To be sure you should try it in both equations. But we have eliminated three of the four choices.\r \n" ); document.write( "\n" ); document.write( "The other tutor seems confused. \n" ); document.write( "He first says that 3,7 is not a solution then while working on d) he says it is then he says that -5,-7 is the solution. \n" ); document.write( " \n" ); document.write( " |
