\n" ); document.write( "a + b + c = -4
\n" ); document.write( "b - c = a
\n" ); document.write( "a + b = -5

\n" ); document.write( "a + b + c = -4
\n" ); document.write( "a - b + c = 0
\n" ); document.write( "a + b + 0 = -5
\n" ); document.write( "-----------------------
\n" ); document.write( "Subtract 1st row from 2nd
\n" ); document.write( "Subtract 1st row from 3rd
\n" ); document.write( "a + b + c = -4
\n" ); document.write( "0 -2b + 0 = 4
\n" ); document.write( "0 + 0 - c = -1
\n" ); document.write( "------
\n" ); document.write( "c = 1
