x = dimes
\n" ); document.write( "y = x-12 = quarters
\n" ); document.write( "---
\n" ); document.write( "10x + 25y = 1100
\n" ); document.write( "10x + 25(x-12) = 1100
\n" ); document.write( "10x + 25x - 12*25 = 1100
\n" ); document.write( "35x = 1100 + 12*25
\n" ); document.write( "x = (1100 + 12*25)/35
\n" ); document.write( "x = 40
\n" ); document.write( "y = x-12
\n" ); document.write( "y = 40-12
\n" ); document.write( "y = 28
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "x = dimes = 40
\n" ); document.write( "y = quarters = 28
