WebJun 6, 2024 · Nonlinear Systems – In this section we will take a quick look at solving nonlinear systems of equations. A nonlinear system of equations is a system in which at least one of the equations is not linear, i.e. has degree of two or more. Note as well that the discussion here does not cover all the possible solution methods for nonlinear systems. WebThe system we will solve is: Equation 1: 2x + y = 8. Equation 2: x – y = 4. Solution: 1.) Let’s isolate x in the second equation. Moving y to the right side of the equation results in x = y + 4. 2.) We may now substitute that value of x into the first equation. portail golfech
