\n" );
document.write( "Hi
\n" );
document.write( "6x + 3y = 33
\n" );
document.write( " 4x + y = 15  OR y = (-4x+15)
\n" );
document.write( "Solving by substitution:
\n" );
document.write( "6x + 3(-4x+15) = 33
\n" );
document.write( "      12 = 6x
\n" );
document.write( "        2 = x   and y = 7  (-4·2 +15) \n" );
document.write( "
