long and tedious using elimination. i guess determinant will do it, but easiest method if you just need a solution is to cheat http://www.wolframalpha.com/input/?i=2x-%28m%2B1%29y%2Bz%3D5+%2C2mx%2By-z%3D1%2C+4mx-5y%2Bz%3D11

simplify you equation first

anonymous · Answer

try and isolate z and then use elimination or substitution based on preference.

wolfram is the quick way to solve this system,  but here is how to do it "by hand" using elimination.
