The original system was
\n" ); document.write( "(i) 6x+y=-12
\n" ); document.write( "(ii) 5x-2y=-10
\n" ); document.write( "step 1 - multiply (i) by 2 to get
\n" ); document.write( "(iii) 12x + 2y = -24
\n" ); document.write( "step 2 - add (ii) and (ii) to get
\n" ); document.write( "(iv) 17x = -34
\n" ); document.write( "solve for x to get
\n" ); document.write( " $\"x+=+-2\"$
\n" ); document.write( "substitute this into (i) to get
\n" ); document.write( "6(-2) + y = -12
\n" ); document.write( "-12 + y = -12
\n" ); document.write( " $\"y+=+0\"$
\n" ); document.write( "So we get
\n" ); document.write( "(-2,0) \n" ); document.write( "

\n" );
