1 x -1 y = 11 .............1
\n" ); document.write( "
\n" ); document.write( "3 x + 10 y = -6 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 10
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "10 x -10 y = 110
\n" ); document.write( "3 x + 10 y = -6
\n" ); document.write( "Add the two equations
\n" ); document.write( "13 x = 104
\n" ); document.write( "/ 13
\n" ); document.write( "x = 8
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x -1 y = 11
\n" ); document.write( "8 -1 y = 11
\n" ); document.write( " -1 y = 11 -8
\n" ); document.write( " -1 y = 3
\n" ); document.write( " y = -3 \r
\n" ); document.write( "\n" ); document.write( "(8,-3)
\n" ); document.write( " \n" ); document.write( "
