You can put this solution on YOUR website!
Here are your two equations
\n" ); document.write( "(i) $\"x%2By=10\"$
\n" ); document.write( "(ii) $\"2x=y-13\"$
\n" ); document.write( "Solve (ii) for y and we get
\n" ); document.write( "(iii) $\"y+=+2x+%2B+13\"$
\n" ); document.write( "Lets solve by substitution of (iii) into (i) as
\n" ); document.write( "(iv) $\"x+%2B+2x+%2B+13+=+10\"$
\n" ); document.write( "Now,
\n" ); document.write( " $\"3x+%2B+13+=+10\"$
\n" ); document.write( " $\"3x+=+-3\"$
\n" ); document.write( " $\"x+=+-1\"$
\n" ); document.write( "Now, we find y as
\n" ); document.write( " $\"y+=+11\"$ \n" ); document.write( "

\n" );
