let x , y be the 2 numbers
\n" ); document.write( " one number is 4 less than another number
\n" ); document.write( "so x= y+4
\n" ); document.write( " but x+y= 100
\n" ); document.write( " put x=y+4 in above equation
\n" ); document.write( " (y+4) +y= 100
\n" ); document.write( " y+4+y= 100
\n" ); document.write( " 2y+4 =100
\n" ); document.write( " subtract 4 on both sides
\n" ); document.write( " 2y+4-4 =100-4
\n" ); document.write( " 2y = 96
\n" ); document.write( " divide with 2 on both sides
\n" ); document.write( " 2y/2 = 96/2
\n" ); document.write( " y= 48
\n" ); document.write( " hence x = 48+4
\n" ); document.write( " =52
\n" ); document.write( " so numbers are 52 & 48 \n" ); document.write( "
\n" );
