24c stamps = x
\n" ); document.write( "37c stamps = y
\n" ); document.write( "x + y = 100...1
\n" ); document.write( "24x + 37y = 3102...2
\n" ); document.write( "Multiply (1) by 37
\n" ); document.write( "37x + 37y = 3700...3
\n" ); document.write( "24x + 37y = 3102...2
\n" ); document.write( "Subtract (2) from (3)
\n" ); document.write( "13x = 598
\n" ); document.write( "x = 46
\n" ); document.write( "Substitute x = 46 in (1)
\n" ); document.write( "x + y = 100
\n" ); document.write( "46 + y = 100
\n" ); document.write( "y = 100 - 46
\n" ); document.write( "y = 54
\n" ); document.write( "There are 46x24c and 54x37c stamps
\n" ); document.write( "Hope this helps.
