2. Let the bigger number = x
\n" ); document.write( " Let the other number = y
\n" ); document.write( " we get x:y = 3:2
\n" ); document.write( " 2x = 3y
\n" ); document.write( " x =(3/2)y\r
\n" ); document.write( "\n" ); document.write( "again (x-8)/(y-10) = 2 (big divided by 10 less than small) = quo 2, rem 8)
\n" ); document.write( "x-8 = 2(y-10)
\n" ); document.write( "x-8 = 2y-20
\n" ); document.write( "x-2y = -20+8
\n" ); document.write( "subst x=(3/2)y,
\n" ); document.write( "(3/2)y - 2y = -20+8
\n" ); document.write( "-(1/2)y = -12
\n" ); document.write( "y = 24 that is it.
\n" ); document.write( "
\n" );
