\n" );
document.write( "Hi,
\n" );
document.write( " x+y = 3
\n" );
document.write( " x-y = -1           |Adding the EQuations to eliminate the y variable
\n" );
document.write( " 2x = 2
\n" );
document.write( "  x = 1  and y = 2    (1 + y = 3) 
\n" );
document.write( "Ordered pair(1,2)  the solution for this System of Equations
\n" );
document.write( "3x=y+2
\n" );
document.write( " x=y+4
\n" );
document.write( "3(y+4) = y+2             ||  Substituting (y+4)  for x
\n" );
document.write( " 3y + 12 = y + 2
\n" );
document.write( "  2y = -10
\n" );
document.write( "   y = -5   and x = -1
\n" );
document.write( "Ordered pair(-1,-5)  the solution for this System of Equations \n" );
