Isolating a variable in one of the equations.
In general, a system of non-linear equations cannot be solved by substitutions.
The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.

Addition and subtraction are mathematical processes. They can be used in equations, which are statements that the values of two mathematical expressions are equal, but they are not equations by themselves.

Nonlinear means something is not in a line. It is a term commonly used in math, meaning two or more equations are not on the same line.
