9 x + 5 y = 2 .............1
\n" ); document.write( "-11 x + 2 y = -27 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -2
\n" ); document.write( "Multiply (2) by 5
\n" ); document.write( "-18 x -10 y = -4
\n" ); document.write( "-55 x + 10 y = -135
\n" ); document.write( "Add the two equations
\n" ); document.write( "-73 x = -139
\n" ); document.write( "/ -73
\n" ); document.write( "x=1.9
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "9 x + 5 y = 2
\n" ); document.write( "17.14 + 5 y = 2
\n" ); document.write( " 5 y = 2-17.14
\n" ); document.write( " 5 y = -15.14
\n" ); document.write( " y = -3.03
\n" ); document.write( " \n" ); document.write( "

\n" );
