document.write( "x+5y=20  and x-y=2
\n" );
document.write( "Solving for x in terms of y using second equation
\n" );
document.write( "x-y = 2
\n" );
document.write( "x = y + 2
\n" );
document.write( "Substituting for x in the first equation:
\n" );
document.write( "x + 5y = 20
\n" );
document.write( "(y+2) + 5y = 20
\n" );
document.write( "6y + 2 = 20
\n" );
document.write( "6y = 18
