Algebra.Com's Answer #26972 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Let the numbers be x and y...then we have \n" ); document.write( "x + y = 54 and \n" ); document.write( "x - y = 18 \n" ); document.write( "Now add the equations and get \n" ); document.write( "2x = 72 and \n" ); document.write( "x = 36 \n" ); document.write( "From this you can see that \n" ); document.write( "y = 18 and we're done... \n" ); document.write( " |
