5 x -2 y = -8 .............1
\n" ); document.write( "1 y = 3 + 2 x ---------2
\n" ); document.write( "/ 1 =
\n" ); document.write( " y = 3 + 2 x
\n" ); document.write( "Substitute y in (1)
\n" ); document.write( "5 x -2 ( 3 + 2 x ) = -8
\n" ); document.write( "5 x -6 + -4 x = -8
\n" ); document.write( "5 x -4 x = -8 6
\n" ); document.write( "1 x = -2
\n" ); document.write( "/ 1
\n" ); document.write( "x= -2
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "5 x -2 y = -8
\n" ); document.write( "5 * -2 -2 y = -8
\n" ); document.write( "-10 -2 y = -8
\n" ); document.write( "-2 y = 2
