\n" ); document.write( "elimination 2a-4b=6
\n" ); document.write( " -a+2b=-3
\n" ); document.write( "

 2a - 4b = 6 -------- eq (i)
\n" );
document.write( "- a + 2b = - 3 ------ eq (ii)
\n" );
document.write( "  a - 2b = 3 -------- Factoring out GCF, 2 in eq (i) ------ eq (iii)
\n" );
document.write( "       0 = 0 -------- Adding eqs (iii) & (ii)
\n" );
document.write( "The system has: INFINITELY many solutions \n" );
document.write( "

\n" );
