The sum of two numbers is 73 \n" ); document.write( "x+y=73; \n" ); document.write( "and their difference (y-x) is thirty-two less (-32) than the smaller number (x) \n" ); document.write( " y-x=x-32 which could be y=2x-32 \n" ); document.write( "if the first really is y-x=x-32 it is correct.\r \n" ); document.write( "\n" ); document.write( "It also could be x-y = y-32 which could be x=2y-32 \n" ); document.write( "so it is the first choice \n" ); document.write( "y-x=x-32 and x-y=32-x are equivalent \n" ); document.write( "multiply by -1 \n" ); document.write( "-1*(y-x)=x-y \n" ); document.write( "-1*(x-32)=32-x \n" ); document.write( "so the first and the third should be accepted as correct. \n" ); document.write( "however the first is in the wording of the problem. \n" ); document.write( " \n" ); document.write( " |
