Here are the original equations:
\n" ); document.write( "(i) $\"2x+-+3y+=+-1\"$
\n" ); document.write( "(ii) $\"1y+=+x+-+1\"$
\n" ); document.write( "---
\n" ); document.write( "step 1 get x and y on the same side and lined up.
\n" ); document.write( "(iii) $\"2x++-+++3y+=+-1\"$
\n" ); document.write( "(iv) $\"-1x+%2B+1y+=+-1\"$
\n" ); document.write( "---
\n" ); document.write( "step 2 - multiply second equation by 2 and add down.
\n" ); document.write( "(iii) $\"2x+-+3y+=+-1\"$
\n" ); document.write( "(v) $\"-2x+%2B+2+y+=+-2\"$
\n" ); document.write( "Now,
\n" ); document.write( "-1y = -3 - -> Y = 3.
\n" ); document.write( "---
\n" ); document.write( "step 3 - sub this value into any above equation to get x.
\n" ); document.write( "x = 4. \n" ); document.write( "

\n" );
