10 x + 11 y = 26.5 .............1
\n" ); document.write( "20 x + 5 y = -27.5 .............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by -5
\n" ); document.write( "Multiply (2) by 11
\n" ); document.write( "-50 x -55 y = -132.5
\n" ); document.write( "220 x 55 y = -302.5
\n" ); document.write( "Add the two equations
\n" ); document.write( "170 x = -435
\n" ); document.write( "/ 170
\n" ); document.write( "x = -2.56
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "10 x + 11 y = 26.5
\n" ); document.write( "-25.59 + 11 y = 26.5
\n" ); document.write( " 11 y = 26.5 + 25.59
\n" ); document.write( " 11 y = 52.09
\n" ); document.write( " y = 4.74
\n" ); document.write( " \n" ); document.write( "
\n" );
