The sum of three positive numbers is 90 and the sum of two of them is the third. Find the numbers if the smallest one is half of the largest.
\n" ); document.write( "x+y+z=90
\n" ); document.write( "2x=z
\n" ); document.write( "x+y=z ; y=z-x ; y=2x-x=x
\n" ); document.write( "x+y+z=90
\n" ); document.write( "x+x+2x=90
\n" ); document.write( "4x=90
\n" ); document.write( "x=22.5 ANSWER 1: x=22.5
\n" ); document.write( "z=2x=45 ANSWER 2: z=45
\n" ); document.write( "y=x=22.5 ANSWER 3: y=22.5
\n" ); document.write( "
\n" );
