2 x -1 y = 6 .............1
\n" ); document.write( "1 x + 1 y = -3 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "2 x -1 y = 6
\n" ); document.write( "1 x + 1 y = -3
\n" ); document.write( "Add the two equations
\n" ); document.write( "3 x = 3
\n" ); document.write( "/ 3
\n" ); document.write( "x = 1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x -1 y = 6
\n" ); document.write( "2 -1 y = 6
\n" ); document.write( " -1 y = 6 -2
\n" ); document.write( " -1 y = 4
\n" ); document.write( " y = -4 \r
\n" ); document.write( "\n" ); document.write( "(1,-4)
\n" ); document.write( " \n" ); document.write( "
