x= Number of small pages
\n" ); document.write( "y= Number of full pages
\n" ); document.write( "
\n" ); document.write( "1 x + 1 y = 21 .............1
\n" ); document.write( "Total words
\n" ); document.write( "1200 x + 1500 y = 27000 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -1500
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-1500 x -1500 y = -31500
\n" ); document.write( "1200 x + 1500 y = 27000
\n" ); document.write( "Add the two equations
\n" ); document.write( "-300 x = -4500
\n" ); document.write( "/ -300
\n" ); document.write( "x = 15
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 21
\n" ); document.write( "15 + y = 21
\n" ); document.write( " y = 21 -15
\n" ); document.write( " y = 6
\n" ); document.write( " y = 6
\n" ); document.write( "x= 15 Number of small pages
\n" ); document.write( "y= 6 Number of full pages
