let the digit in tens place be x
\n" ); document.write( "& in the units place be y
\n" ); document.write( "..
\n" ); document.write( "10y+x=10x+y+36
\n" ); document.write( "9y-9x=36
\n" ); document.write( "/9
\n" ); document.write( "y-x=4.....................1
\n" ); document.write( "...
\n" ); document.write( "x+y=3(x-y)
\n" ); document.write( "x+y=3x-3y
\n" ); document.write( "2x-4y=0
\n" ); document.write( "/2
\n" ); document.write( "x-2y=0....................2\r
\n" ); document.write( "\n" ); document.write( "Add equation1 & 2
\n" ); document.write( "-y=4
\n" ); document.write( "y=-4
\n" ); document.write( "plug value of y in 1
\n" ); document.write( "y-x=4
\n" ); document.write( "-4-x=4
\n" ); document.write( "x=-8\r
