You can put this solution on YOUR website!
We have the following equations:
\n" ); document.write( "(i) $\"+y+=+x+\"$
\n" ); document.write( "(ii) $\"+y+=+-x%2B2+\"$
\n" ); document.write( "substitute (i) into (ii) as
\n" ); document.write( "(iii) $\"x+=+-x+%2B+2\"$
\n" ); document.write( "solve for x as
\n" ); document.write( " $\"2x+=+2\"$
\n" ); document.write( " $\"x+=+1\"$
\n" ); document.write( "Now we find y.
\n" ); document.write( " $\"y+=+1\"$
\n" ); document.write( "the coordinate is (1,1) \n" ); document.write( "

\n" );
