The given equatins are,
\n" ); document.write( " x-1=y+1 ...(1)
\n" ); document.write( " x+1=2(y-1)...(2)
\n" ); document.write( "(1)-(2)=> -1-1 = y+1-[2y-2]
\n" ); document.write( " -2= y+1-2y+2
\n" ); document.write( " -2 = -y+3
\n" ); document.write( " y = 3+2
\n" ); document.write( " y = 5
\n" ); document.write( "Substituting in (1), x-1 = 5+1
\n" ); document.write( " x-1 = 6
\n" ); document.write( " x = 6+1
\n" ); document.write( " x = 7
\n" ); document.write( "Therefore the solution is (7,5) \n" ); document.write( "

\n" );
