\n" ); document.write( "\"3x%2B9y+=+138\" [1]
\n" ); document.write( "\"8x%2B5y+=+178\" [2]

\n" ); document.write( "It might not end up being any help... but divide the first equation by 3 to make the numbers smaller:

\n" ); document.write( "\"x%2B3y+=+46\" [3]

\n" ); document.write( "Multiply [3] by -8 and add the resulting equation to [2]; that will eliminate x.

\n" ); document.write( "\"-8x-24y+=+-368\" [4]
\n" ); document.write( "\"8x%2B5y+=+178\" [2]
\n" ); document.write( "\"-19y+=+-190\" [4]+[2]
\n" ); document.write( "\"y+=+10\"

\n" ); document.write( "Plug y=10 in either of the original equations to solve for x.

\n" ); document.write( "I leave that part to you to finish the problem....

\n" ); document.write( "
