THE GIVEN EQUATIONS ARE \r
\n" ); document.write( "\n" ); document.write( " 3x -2y =11
\n" ); document.write( " -x +6y = 7
\n" ); document.write( "to find the variables x & y,\r
\n" ); document.write( "\n" ); document.write( " try to make any one of the co-efficients of x or y as same but with opposite sign.(to make x co-efficients the same,multiply the second equation by 3)\r
\n" ); document.write( "\n" ); document.write( "therefore we get ,
\n" ); document.write( " 3x -2y = 11
\n" ); document.write( " -3x + 18y = 21
\n" ); document.write( " TO solve,add the equations ,
\n" ); document.write( " we get 16y = 32 (3x-3x get cancelled)
\n" ); document.write( " y= 32/16
\n" ); document.write( " = 2.
\n" ); document.write( " put y= 2 in first equation,
\n" ); document.write( " we get,
\n" ); document.write( " 3x -2(2) = 11
\n" ); document.write( " 3x = 11 +4
\n" ); document.write( " x = 15/3
\n" ); document.write( " = 5.
\n" ); document.write( " the values are x = 5,y = 2.\r
