Let the two numbers be a and b respectively
\n" ); document.write( " From the 1st sentence
\n" ); document.write( " a+b = 100.......(1)
\n" ); document.write( " From the 2nd sentence
\n" ); document.write( " a = 4(b)
\n" ); document.write( " a = 4b
\n" ); document.write( " a-4b = 0...........(2)
\n" ); document.write( " Eliminate equation (2) from equation (1)
\n" ); document.write( " 5b = 100
\n" ); document.write( " b = 100/5
\n" ); document.write( " b = 20
\n" ); document.write( " Substitute b = 20 in equation (2)
\n" ); document.write( " a-4b = 0
\n" ); document.write( " a-4(20) = 0
\n" ); document.write( " a-80 = 0
\n" ); document.write( " a = 80
\n" ); document.write( "Since a and b represented the two numbers
\n" ); document.write( "Therefore the numbers are 80 and 20
\n" ); document.write( "
\n" );
