Algebra.Com's Answer #131402 by EMStelley(208)![]() ![]() You can put this solution on YOUR website! If the two numbers are x and y, their sum being 64 can be written as \n" ); document.write( "x+y=64 \n" ); document.write( "and their difference being 14 can be written as \n" ); document.write( "x-y=14 \n" ); document.write( "So we need to solve the system \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "This system lends itself to the addition method, so let's add the two equations, resulting in \n" ); document.write( " \n" ); document.write( "So x=39. To find y, you simply plug in x=39 to either one of the original equations. I will use the first one. \n" ); document.write( "39+y=64 \n" ); document.write( "y=25. \n" ); document.write( "So the two numbers are 39 and 25. \n" ); document.write( " |
