$\"2x+%2B+3y+=+5\"$
\n" ); document.write( "(a,3) means when $\"x+=+a\"$ , $\"y+=+3\"$
\n" ); document.write( "Plug $\"x+=+a\"$ , and $\"y+=+3\"$ into the equation
\n" ); document.write( " $\"2a+%2B+3%2A3+=+5\"$
\n" ); document.write( " $\"2a+=+25+-9\"$
\n" ); document.write( " $\"2a+=+16\"$
\n" ); document.write( " $\"a+=+8\"$ \n" ); document.write( "
