Algebra.Com's Answer #368574 by mathsmiles(68)![]() ![]() You can put this solution on YOUR website! Let X and Y be the two positive numbers.\r \n" ); document.write( "\n" ); document.write( "X = 5Y. \n" ); document.write( "Since X is larger (they're both positive), we can set up the difference equation as follows:\r \n" ); document.write( "\n" ); document.write( "X - Y = 224.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now let's substitute for X from the first equation: \n" ); document.write( "(5Y) - Y = 224 \n" ); document.write( "4Y = 224 \n" ); document.write( "Divide both sides by 4 giving \n" ); document.write( "Y = 56 \n" ); document.write( "X = 5 times 56 = 280\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Checking our answer: \n" ); document.write( "280 - 224 = 56 Correct! \n" ); document.write( " |
