2 x -1 y = 16 .............1
\n" ); document.write( "-1 x + 2 y = -8 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 2
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "4 x -2 y = 32
\n" ); document.write( "-1 x 2 y = -8
\n" ); document.write( "Add the two equations
\n" ); document.write( "3 x = 24
\n" ); document.write( "/ 3
\n" ); document.write( "x = 8
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + -1 y = 16
\n" ); document.write( "16 + -1 y = 16
\n" ); document.write( " -1 y = 16 -16
\n" ); document.write( " -1 y = 0
\n" ); document.write( " y = 0 \n" ); document.write( "

\n" );
