4 x + 8 y = -8 .............1
\n" ); document.write( "
\n" ); document.write( "-3 x + 6 y = 8 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 3
\n" ); document.write( "Multiply (2) by -4
\n" ); document.write( "12 x 24 y = -24
\n" ); document.write( "12 x -24 y = -32
\n" ); document.write( "Add the two equations
\n" ); document.write( "24 x = -56
\n" ); document.write( "/ 24
\n" ); document.write( "x = -7/3
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "4 x + 8 y = -8
\n" ); document.write( "-9 + 8 y = -8
\n" ); document.write( " 8 y = -8 + 9
\n" ); document.write( " 8 y = 1
\n" ); document.write( " y = 1/6
\n" ); document.write( "x=-7/3 y =1/6
\n" ); document.write( " \n" ); document.write( "

\n" );
