\n" );
document.write( "Hi,
\n" );
document.write( "A= =
\n" );
document.write( "I. find value of determinant =  a1(b2c3-c2b3) - b1(a2c3-c2a3) + c1(a2b3-b2a3) = 28
\n" );
document.write( "II. Then Apply formula for the Inverse:
\n" );
document.write( " = 1/d\r
\n" );
document.write( "\n" );
document.write( "  = 1/28
\n" );
document.write( " \n" );
document.write( "
