I think you can finish it now. Share. Solving a System of Nonlinear Equations Using Elimination We have seen that substitution is often the preferred method when a system of equations includes a linear equation and a nonlinear equation. However, when both equations in the system have like variables of the second degree, solving them using elimination by addition is often easier

Nonlinear equations to solve, specified as a function handle or function name. fun is a function that accepts a vector x and returns a vector F, the nonlinear equations evaluated at x. The equations to solve are F = 0 for all components of F. The function fun can be specified as a function handle for a file x = fsolve (@myfun,x0) The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain in almost every real situation. [18] [19] In some cases, such as one-dimensional flow and Stokes flow (or creeping flow), the equations can be simplified to linear equations. We know how to solve a linear algebraic equation, x= −b/a, but there are no general methods for ﬁnding the exact solutions of nonlinear algebraic equations, except for very special cases (quadratic equations are a primary example).
