It is required to solve 170 nonlinear algebraic equations simultaneously. The Jacobians of these are difficult to evaluate. The provided initial guess may also be a poor guess. Under such conditions which method should be used to give a solution in a sufficiently fast time as possible? Maximum Value of time step to be used = 0.1seconds

Since equations are non-linear, you can use gauss seidel iteration method.

The easiest way to answer this question would be to make the coefficients of y the same. therefore times all parts of the bottem equation 2x+y = 8 by 3, making it 6x + 3y = 24. Now u can minus the bottom equation from the top equation to cancel out the 3y making x the subject. -2x = -3 would be what is left. divide -3 by -2 to give an answer for x, the answer being 1.5 (3/2) Now substitute 1.5 into the easiest equation which in this case would be equation 2, 2x+y = 8..... (2 x 1.5) + y = 8 solve the equation 3 + y = 8 y = 8-3 y = 5

Will come back.
You said Maximum Value of time step to be used = 0.1seconds
There are mathematical programs.
How about Math Cad.
Long hand Trial and error, still go crease.
Combination Trial and error and metrics solution.

What is a sufficiently fast time? A few seconds, a hour, next year?
