-1 x -1 y = 5 .............1
\n" ); document.write( "
\n" ); document.write( "1 x -5 y = -9 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 5
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-5 x -5 y = 25
\n" ); document.write( "1 x -5 y = -9
\n" ); document.write( "Add the two equations
\n" ); document.write( "-4 x = 16
\n" ); document.write( "/ -4
\n" ); document.write( "x = -4
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-1 x -1 y = 5
\n" ); document.write( "4 -1 y = 5
\n" ); document.write( " -1 y = 5 -4
\n" ); document.write( " -1 y = 1
\n" ); document.write( " y = -1
\n" ); document.write( "x= -4
\n" ); document.write( "y= -1
