\n" ); document.write( "relative speed of cars:
\n" ); document.write( "s = d / t
\n" ); document.write( "s = 300 / 3
\n" ); document.write( "s = 100 mph
\n" ); document.write( "---
\n" ); document.write( "x + y = 100
\n" ); document.write( "x = y + 10
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 100
\n" ); document.write( "x - y = 10
\n" ); document.write( "---

\n" ); document.write( "x= 55
\n" ); document.write( "y= 45
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "car-1 = 55 mph
