-2 x + 1 y = -6 .............1
\n" ); document.write( "1 x + 1 y = 0 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -1
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "2 x -1 y = 6
\n" ); document.write( "1 x 1 y = 0
\n" ); document.write( "Add the two equations
\n" ); document.write( "3 x = 6
\n" ); document.write( "/ 3
\n" ); document.write( "x = 2
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-2 x + 1 y = -6
\n" ); document.write( "-4 + 1 y = -6
\n" ); document.write( " 1 y = -6 + 4
\n" ); document.write( " 1 y = -2
\n" ); document.write( " y = -2\r
\n" ); document.write( "\n" ); document.write( "equation1
\n" ); document.write( "when x= 0 y= -6 ( 0 , -6 )
\n" ); document.write( "when y = 0 x= 3 ( 3 , 0 )
\n" ); document.write( "Equation 2
\n" ); document.write( "when x= 0 y= 0 ( 0 , 0 )
\n" ); document.write( "when y = 0 x= 0 ( 0 , 0 )\r
