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