Algebra.Com's Answer #411113 by kevwill(135)![]() ![]() You can put this solution on YOUR website! Let x and y be the two numbers. There are two cases: (1) we subtract y from x to get the difference (y is the minuend and x is the subtrahend), and (2) we subtract x from y to get the difference (x is the minuend and y is the subtrahend).\r \n" ); document.write( "\n" ); document.write( "In the first case: \n" ); document.write( "n = (x+y) - (x-y) \n" ); document.write( "n = x + y - x + y \n" ); document.write( "n = 2y\r \n" ); document.write( "\n" ); document.write( "In the second case: \n" ); document.write( "n = (x+y) - (y-x) \n" ); document.write( "n = x + y - y + x \n" ); document.write( "n = 2x\r \n" ); document.write( "\n" ); document.write( "So we can say that the answer is twice the the number we choose for the subtrahend when we find the difference of the two numbers. \n" ); document.write( " \n" ); document.write( " |
