- Homework Statement
- consider the following system of equations;
##x+2y+mz=0##
##x+3y-z=3##
##mx+8y+5z=6##
where ##m## is a scalar. For what values of m, does the system have a (i) unique solution (ii)many solutions (iii) no solution
- Relevant Equations
- simultaneous equations
...##2y-2z-2mz=6##
## 2y-2z-2mz= mx+8y+5z##
i then let,
##-2z-2mz=5z##
##m=-7/2##
##→2y=mx+8y##
##7x=12y##
## 2y-2z-2mz= mx+8y+5z##
i then let,
##-2z-2mz=5z##
##m=-7/2##
##→2y=mx+8y##
##7x=12y##
