sunny: i have two equations and 3 variables x+2*y+3*z=0 and 2*x+ 3*y+3*z=0... i.e. infinite solutions .right? i tried reporting my answer in parametric form but by two different methods i got two different parametric solution i.e.(3*t,-3*t,t) and (-p,2p,-p). for any value of p or t the equations are satisfied.. why is it happening.
