solve the system: 4x+3y-11z=8.................1
\n" ); document.write( "x+y-3z=3.......................2
\n" ); document.write( "there are 2 eqns. and 3 unknowns.hnce we shall get infinite solutions.
\n" ); document.write( "eqn.1 - 3*eqn.2
\n" ); document.write( "4x+3y-11z-3x-3y+9z=8-9=-1
\n" ); document.write( "x-2z = -1...........................3
\n" ); document.write( "hence take any value for x say 1
\n" ); document.write( "1-2z=-1
\n" ); document.write( "z=1
\n" ); document.write( "put in eqn.2
\n" ); document.write( "1+y-3=3
\n" ); document.write( "y = 5
\n" ); document.write( "x=1,y=5,z=1 is a solution set.
\n" ); document.write( "similarly give any value to x and find y and z using the eqns.3 and 2
\n" ); document.write( "in general we can say that
\n" ); document.write( "x=x(any value);y=(x+9)/2 ;z=(x+1)/2 is a solution set
\n" ); document.write( " \n" ); document.write( "
\n" );
