I have a simple set of nonlinear equations
1) 3x = 30
2) x+2y = 20
3) x + y*z = 15
Clearly the solution to this is (10,5,1) but I want to find a robust way to solve this type of problem [A]x=b (where [A] is a simple function of x) which doesn't involve numerically solving using Newtons method.
{{3,0,0},{1,2,0},{1,z,0}} {{x},{y},{z}} = {{30}, {20}, {15}}
