\n" );
document.write( "2x = y + 11
\n" );
document.write( "3y + 7 = -(1/2)x \r
\n" );
document.write( "\n" );
document.write( " 2x - y = 11
\n" );
document.write( "-2x - 12y = -7*-4  |multiplying 2nd EQ thru by -4 to eliminate x
\n" );
document.write( "    -13y = 39
\n" );
document.write( "       y = -3  and x = 4   ( x = (y+11)/2\r
