Algebra.Com's Answer #773947 by Boreal(15235) You can put this solution on YOUR website! numbers are x and y, and they add to 21 (3/4) x+y=21 (3/4) so x=21 (3/4)-y \n" ); document.write( "x+(2/3)y=15 \n" ); document.write( "therefore x=15-(2/3)y \n" ); document.write( "but from the first, x=21(3/4)-y as well. \n" ); document.write( "since x equals either, they both equal each other \n" ); document.write( "15-(2/3)y=21(3/4)-y \n" ); document.write( "(1/3)y=6 (3/4), and y is 3 times 6 3/4 or 20.25\r \n" ); document.write( "\n" ); document.write( "If one number is 20.25, the other is 1.5 to add to 21 3/4 \n" ); document.write( "1.5 + (2/3)20.25=1.5+(2/3)*81/4=1/5(54/4)=1.5+13.5=15 \n" ); document.write( " \n" ); document.write( " |
