document.write( "- 3x + 7y = - 16 -------- eq (i)
\n" );
document.write( "- 9x + 5y =   16 -------- eq (ii)
\n" );
document.write( "Is the 2nd plus sign in the 2nd equation supposed to be \"=\"? If so, then the most convenient method is to:

document.write( "1) Multiply eq (i) by - 3, creating eq (iii)
\n" );
document.write( "2) Sum eqs (iii) &  (ii), thus eliminating x
